Restricting selection of items on selection of specific item in Multiselect - flutter

I am using multiselect pugin to implement multiselect list in my flutter project. In the project I want to add the functionality like,
the option in list are all, first, second, third
Now when I select the all option then the multiselect should restrict the user from selecting other options as he has already selected all option. and when user selects the remaining options from the list except all then he should be restricted from selecting all.
Is it possible to achieve in flutter? I've tried few options like restricting the list showing values or adding vlidation but not getting expected result.
The plugin I am using is: https://pub.dev/packages/multiselect
Please help me with the slution...
I wouldn't mind using custom build multilist with expected properties.

How can I add a custom column menu tab in ag-grid?

Is there a way to add a custom column menu tab with my own favourite icon which on click would render my custom react component?
something like
myColDef.menuTabs: ['generalMenuTab', 'filterMenuTab', 'myCustomMenuTab']
FYI I'm using v12.0.2
What you're after can't be done I'm afraid. The grid supports React components in all sorts of ways (renderers, editors, filters etc), but not via the column menu.
I've updated the docs page to remove the gibberish issue - it'll be fixed properly in the next release, thanks for highlighting this.
This would be helpful to have. In particular for us, we'd like to filter based off row properties, and not row values. Creating our own tab to filter by cell colors that we have assigned with our own set of labels would be useful.
I agree that it would be a nice feature to have. Apparently, there's no quick out-of-the-box solution to do it. The only workaround I see is to implement your own custom Header component which would display any buttons your want.
There you can put a button to open your own custom menu, which you can implement as any regular UI component. It also means you'll need to manually implement all standard menu options that Ag-Grid provides out of the box if you need them.

Material-ui List select multiple items

As shown in the documentation example you can implement a selectable List.
I was wondering how would one be able to make the list to support multiple selections.
The method that was used in the example is makeSelectable. There doesn't seem to be any documentation regarding that method and I wasn't able to find anything substantial in the issues of their git project.
Any help will be appreciated.
Create a state variable selectedItems to keep track of selected items of the list.
ListItem supports checkboxes, so you can create a checkbox for each ListItem, add an onCheck handler to it and pass to it a unique value to identify which checkbox is checked and based on that you can modify the state variable selectedItems.
Alternatively, you can use Menu in place of List as it has the property multiple. You can set it to true and that's it.

Show/Hide different fields Based on dropdown value in Magnolia content app?

I have created a content app in which I am able to show and hide different fields using radio buttons but how to Show/Hide different fields Based on the dropdown value in Magnolia content app?
For radio button and fields i used below class info.magnolia.ui.form.field.definition.SwitchableFieldDefinition
and for transformer class i used
info.magnolia.ui.form.field.transformer.composite.DelegatingCompositeFieldTransformer
but now i want to use
info.magnolia.ui.form.field.definition.SelectFieldDefinition
instead of SwitchableFieldDefinitionbut I am unable to do so with any of the transformer class.
I also searched and found similar thread here but it has the incomplete answer!
According to https://documentation.magnolia-cms.com/display/DOCS/Switchable+field you can define a property named "selectionType" with the value "select".
I haven't tested that though.
If you have a look in SwitchableFieldDefinition, it looks promising though, because there's really a property with that name and it just defaults to "radio" but can be overwritten.

Customise your layered navigation functionality
An example of layered navigation with your problem
You have 3 attributes:- (Category,Color, Manufacaturer) Color is dependent on category and Manufacturer in Color
So when you pass #cat=5 the ajax call will filter out the products. Also filter out the second dropdown according to available products existing color.. Then similarly pass #cat=5&color=23.... so on
This filteration is already done in layered navigation. You just have to custmise your code to use this in dropdown
:)

Is there a simple way to have a GWT CellList with multiselection and check boxes

I'v got a lot of different lists of objects which I must provide to the user. The user has the possibility to select multiple elements in this lists. A check box in front of every item in the list is definitely needed.
It seams to me that the standard solution for this problem is a CellTable or a DataGrid but it is so very inconvenient to implement wit all the set-up stuff. Isn't there any simple solution like the ListBox where I got the possibility to enable the check box / multi-selection feature in just a few lines of code?
Within GWT Widgets
Option 1
ListBox -> Single & Multi Selection - No Checkbox.
Option 2
CellTable/DataGrid -> Single & Multi Selection with Selection Checkbox.
Option 3
CellList -> Single & Multi Selection & Customized Cells with CheckBox
