I've just started on a new project of my own.
What I would like to do is, on large screens, having a button activating a modal window BUT, on smaller screen (mobiles), I would like that modal window to become an off canvas section and when the button is clicked, the off canvas slides in from the side. Within that modal/off canvas part, there will be a form to fill out. (there will actually be multiple buttons that will need to activate the feature. Think something like multiple thumbnails with each a button to let viewers add comments)
I'm using Bootstrap 3 as my base framework. I would like to minimise the javascript (jQuery) functionalities but I understand I can't completely.
Questions I have,
do I have to create two HTML sections, one for the modal and one for the off canvas and then programatically hide/show according screen size?
Would it be best to create the form and then thru javascript, add the proper HTML around it according screen size? (though I think this option would be a tough to implement as my javascript skills are "advance beginner" at best)
How would I make the same button switch activation of the modal window or the off canvas form?
It seems to me that I need to detect screen size, no matter how I do the above, what would be the best way to detect the screen size, the safest and surest way?
Thanks for any insights you guys might have on this.
You will have to show code in your questions here, so i also vote to close your question.

Angular JS decouples Twitter's Bootstrap from javascript. See: http://angular-ui.github.io/bootstrap/

Take a look to the Responsive Utilities: http://getbootstrap.com/css/#responsive-utilities
The screen detection of Twitter's Bootstrap is based on CSS media queries.

To give the same button different function based on sceensize you will need javascript / jQuery. See: Get the size of the screen, current web page and browser window you also could consider to use something like enquire.js, see also http://bassjobsen.weblogs.fm/responsive-banner-ads-2/
Or create two buttons and hide / show them with the the Responsive Utilities.

I am working on xamarin.forms. I am using Master detail page. In menupage of MasterDetailPage I have some menu items that are listed. At the bottom of the Menu list I placed a button on menu page. Now I need to open a popup on click of that button. I am trying with PopupLayout but not able to get any success.
Please tell me how I can open a custom popup box at the click of the button that is placed in menu page?

Without going into separate, native projects for all platforms you are targeting (such as Android, iOS, UWP...), you cannot pop out custom UI content over existing pages in Xamarin.Forms out of the box. You would need to bring in additional references or get creative with the AbsoluteLayout control.
Here are a few options you have:
Simple popup with message and or option selection
If all you need is a simple popup message or a list of buttons, you should look into the native DisplayAlert and DisplayActionSheet methods. They are built into Xamarin.Forms and work really well for these simple cases.
More complex popup dialogs
For anything more complex than that, there is the excellent UserDialogs project: ACR UserDialogs github page
It will give you support for various loading dialogs, date, time pickers, action sheet, success/info/error toasts and more.
Fully custom UI markup with AbsoluteLayout
There is a technique where by you prepare the underlying page with a root absoltue layout, which enables you to dynamically add new UI on top of all other controls on your page. This is fiddly and can ruin your performance if you are not careful. This is also the approach that the PopupLayout control that you mentioned uses. If done properly, this can be a good solution, but I don't recommend it as it involves additional complexity on each page that hosts the popup content.
Fully custom UI popup on native projects
Your most flexible option, as always, is to fall back to the native projects. This would involve coding up the popup logic on each separate platform that you are targeting, then using DependencyService (or one of the other techniques) to call into it from the shared project. For this you should look at samples and tutorials for popups on separate native platforms as it gets pretty broad and goes way outside the topic of this question.
I've been trying to find a solution but I can't find any.
I'll use basic examples so anyone who knows ionic can understand my problem well.
ionic start myApp tabs will create a new project with tabs ready to go.
Those tabs are Dashboard, Chat and Settings.
When you go to the Chat Tab you will then select a person to view its chat content (which directs you to the Chat-Detail Page in actuallity)
I wanted to hide the ion-tabs directive when I go to the chat-detail page so I can force the user to use the Back button instead of clicking anything on the ion-tabs.
Simply put : you will have a hard time doing that. At best it will not look good, IF you succeed to hide using css (I did it, and really, it's not pretty). Basically you would need to define a variable on the parent scope, that changes when entering the chat-detail state, and bind it to ng-class directives on multiple elements (the ion-tabs to hide it, the ion-content to translate it up to cover the area where the tabs were, and add some transition to make it not too brutal).
The logical thing to do would be to have the chat-detail state not being a child of the state containing the tabs. The problem you will have, though, is that there is a huge bug going to / from tabbed state. See details here : https://github.com/driftyco/ionic/issues/2997
At the end of this discussion you can find some posts by Jason and Jerrybels (that would be me), that could lead you on the right way to do it. Basically, you will have to get rid of the ion-tabs directive, and use Ionic's CSS for tabs instead, doing all the states manipulations yourself.
Good luck !
You can use "hidden" attribute of ion-tab like this -
<ion-tab hidden={{condition}}" />
Using this we can show/hide tab.
I am using addthis thirdparty tool for facebook and twitter like button , The twitter like button rendering parallely with the page but facebbok button renders a bit late, after the whole page, I am using it like that :
a class="addthis_button_facebook_like" fb:like:href="#"
Is there a way for rendering it same time with the whole page ?
Unfortunately, it isn't possible to guarantee when the buttons will be rendered. All the buttons will load at different times depending on how fast the resources (JS/CSS) are loaded and how quickly the code executes to render the buttons. This is done to make sure your page always load and doesn't get blocked by the buttons loading. The reverse could happen where Twitter loads slowly and Facebook loads quickly. Is there a functional reason for wanting them to load at the same time? If so, you could "hide" the div containing all the buttons and then have them all appears after a certain amount of time to increase the likelihood that all buttons have been rendered. I hope that makes sense.
I'm working something like a dynamic menu, where you click some radio buttons and it shows a specific form, each radio control matches to a different form.
Examples from the showcase always base themselves on the Tabs widget and I don't need that behaviour.
I opted for placing all the forms inside one Canvas and hide/show them accordingly (Not sure this was the best idea, if someone knows better I would like to hear it)
Now my problem is that every onClick event has to .show() one form and .hide() the other 9. that is annoying.
Is there a way to "get" the current displayed child in the Canvas and hide it?
If what you want is basically mutex display, you could put all the components as members of a Layout instead of a Canvas, then use setVisibleMember(). That hides all other members.
In my iPhone app, I must have around 9-15 different views, all available from a main menu. I started yesterday with a simple tab bar controllers, but they are only ideal with 6-7 views. Which controller can I use? Is there a nice one for my needs?
Edit: I am talking about around 9-15 menu-points for my application.
Each point is a single, categorizable function. I though about something like the Facebook app, where the app shows 2 menu-pages (slideable) and 9 icons on each page, each with another view / function in it.
look for cocoacontrols.com . i think you will find your need there .....
I think the component you are looking for(the same used in facebook app) is in the three20 library. Its called Launcher. It's like having iphone springboard inside the app. I'd go with that.
Can your views be split into categories? If so, I would suggest using the tab bar tabs as categories, and then using a table view as a menu in each tab.
You could also try using a page control, but 9-15 views seems like they would be obnoxious to navigate with a page control.
I understand that you need to have access to those "views" all the time. You can do what an iphone CNN app does. It uses horizontal scroll, where it has lot's of "views".
This is propably the most challenging part of writing an app for mobile phones. At least i find it not that easy to find the perfect user interface. Espcially if you have so much content and navigation to show.
I think the best way to solve this problem is to write your own navigation. If you want to use something similar like the facebook app - this is not so hard.
Take a UIScrollView in combination with the UIPagingControl. Create a new View for your buttons or whatever you want your user to see and put it in the scroll view. Enable paging for the UIScrollVIew and your almost done. Maybe it's not the easiest way - but in the end it's the most flexible way. You can decide what you want to show and you dont have to be dependent on what some other developer wrote.
Just a thought :)
// Edit: Just read in another question about appLauncher. This might be such a control you are looking for.
