How can I style a dijit.form.Select drop down menu if a use the HTML markup.
<select id="sourceselect" dojoType="dijit.form.Select" style='width:200px' onChange="changeDetected();">
</select>
To make it clear it want to style the drop down menu that is filled with the content. I want to change the height of that menu and have a scroll bar if the height is exceeded.
I am using Dojo version 1.6. Here is a Fiddle example: http://jsfiddle.net/NH7dd/.
Edit: Why the minuses?
The menu that is generated by Dojo is placed in the root of the DOM node. It's a common mistake that the menu is somehow relative positioned towards the textfield, but it isn't.
If you wish to change the style of the menu, then you could use the following CSS selector:
div[dijitpopupparent="sourceselect"] > .dijitMenu {
/** Your CSS */
}
The reason this works is because the menu is wrapped inside a dijit/popup. This popup allows displaying/hiding the menu and as you can see it has an attribute dijitpopupparent which has the original ID of the field.
I also updated your JSFiddle, which now looks like this. But I don't really recommend changing the behavior of the menu like this, since you might mess up the original functionality/behavior of the combobox. I mean, right now I have problems going to certain values because one "scroll tick" already passes a value. With the updated style I can't even properly select "2" anymore.
EDIT: In the updated JSFiddle the scrollbar will always be visible, if you want the scrollbar only to appear when there are more options, then change overflow-y: scroll to overflow-y: auto.
You can set the property for maxHeight.
<select id="sourceselect"
dojoType="dijit.form.Select"
data-dojo-props="maxHeight: 200"
style='width:200px'
onChange="changeDetected();">
</select>
Also, the newer syntax for dojo is "data-dojo-type" instead of "dojoType".
Here is JSFiddle showing the maxHeight property. (I used dojo 1.9, but maxHeight is available in 1.6)

I am using a MUI TextField component with a select prop, and do not manage to position the options menu below the input field (the menu covers the input field when open). This happens in MUI's own sandbox as well:
https://codesandbox.io/s/9oqjs?file=/demo.js:1442-1496
In the sandbox, in all of the examples to the left, the menu covers the input field. It doesn't happen in the examples to the right, as these use the native select html tag, but this comes at the price of using the browser's menu.
Any idea how to position the menu correctly without the native select?
Many thanks!
It looks like Position of <MenuItems> under the Material-ui <Select> component can answer your question.
I also found that if the list of MenuItems is too long to fit under the TextField, the Menu will expand vertically over the TextField to accommodate the list. Adding a max-height to the menu can fix that.
<TextField
...
select={true}
SelectProps={{
MenuProps: {
sx: { maxHeight: '50%' }
}
}}

I'm using the Angular UI Bootstrap typeahead to display a customized list of suggestions as the user types into a text input form control. This form control exists inside a div using jQuery slimScroll in order to maintain a constant div size despite the size of its contents fluctuating. I really hoped the typeahead would display over everything like a regular html select dropdown, but unfortunately it does not, as can be seen in this plunker. I've tried futzing around with the z-index and adjusting the position and display properties; all fruitless endeavors.
Does anybody know how to get the typeahead popup to display over its parent border? If not, is there a way I could coerce the select tag to display HTML content so I can include glyphicons, emphasized text, etc. in the list of suggestions?
The problem is with the slim scroll - you are inside a div with relative position and overflow hidden (think of it as an iFrame). There is a small workaround...
You could, essentially set the position of the generated UL (.dropdown-menu) to fixed, set a height for it, then set an overflow:scroll...
It would work in some scenarios where the input field has a fixed position... otherwise you'd need to control where the input is and adjust the position of the auto-complete to follow, and a whole other bunch of nasty scripts.
Without looking at your application, I cannot understand why your have this particular architecture, but I can say that there must be cleaner options for handling autocomplete outside of slimscroll.
I just set typeahead-append-to-body="true" on the typeahead control and it worked. Not sure exactly why, but it's certainly a simple solution.
I was having the same problem as this question:
jQuery Mobile 1.1.1 Custom Select Menu - Placeholder Text not Visible
The above question solved my problem by telling me to use 'http://code.jquery.com/mobile/latest/jquery.mobile.min.js'. That solved my original problem but caused another.
The select menu is always displayed and doesn't center on the select item like it did before.
After:
Does anyone know how to fix this. I think I might be able to hide and show the menu if that was the only problem that I was having, but even when selected it is not in the right position. It should be centered over the select element both horizontally and vertically (if given enough vertical space).
This is caused by the latest release of JQuery, but I also can't download 1.1.1 because it causes the original problem that I had which was solved in the other question.
Looks like the menu is displaying relative to the rest of the content - Try adding a css line on there
position:absolute;
on the menu structure - Another good way to test this would be to load up your site in google chrome and use firebug to see why the menu is positioning lower than the "click point." Just on glance it appears that the menu is appearing relative.
i have a list box in my application, but i don't want to show the
vertical scroll bar on the right side, is there any way to remove it?
here is my code:
<g:ListBox visibleItemCount='3' width="15em">
<g:item>Last 7 Days</g:item>
<g:item>Last Week</g:item>
<g:item>Last Month</g:item>
</g:ListBox>
Thanks!
I believe the correct answer to this is simply: "You can't"
The ListBox (HTML Select) vertical scroll bar cannot be completely removed.
You could create your own custom control using a div to do the same thing. but I believe that may be outside of the abilities of GWT.
Hide vertical scrollbar in <select> element
Will provide additional information.
I assure you the correct answer to this is simply: "You can".
Just add the line:
overflow: hidden !important;
to your css style sheet and make sure your visible item count is higher than it's total item count.
I am making a vertical Menu using GWT MenuBar and selection of particular MenuItem shows content on the right, I am trying to make something similar to TabPanel, but with Tabs on left instead of being on top. Now, since I've got the Menu items and actions in place, I want to remove the effect of hovering over and changing color, and keep that menu item selected which was clicked last and whose content is loaded on the right.
I am open to any comments, if you have a better solution to implement this, using some other components(with-in) GWT, please drop in a comment with your suggestions, I'll really appreciate that.
Or if you can just tell me how can I disable this effect, of hovering and sticking to only that selection, That would be awesome too..
Thanks to everyone, taking time to read this and suggesting a solution.
It's all defined in the CSS of your GWT's theme (probably the default one), so it's a matter of overriding those styles - make sure it's not the other way around :) Inspect the code with a tool like Firebug to see what's exactly being set and change that.
