DropDown with disable item

Radzen.Blazor Components

Hello!

Is it posible in Dropdown disable some Item in the list? the idea is to show some items in dropdown but not selectable.

similar to:

<option value="-1" style="color:gray;" disabled="true">Option 4</option>

thank you!

regards

Not possible since the DropDown can create items only runtime based on provided Data unlike the select element where you can declare options manually.

@enchev ok, you are right,

One posible suggestion to code could be to add one new parameter DisabledProperty, as Dropdown have TextProperty, ValueProperty ?

TIA!

HI @enchev

I have tried to do it using <template/> but I can't do it work. I can do it in chrome developping tools adding class ui-dropdown-item-disabled to some <li/> item generated to test and it worked.

.ui-dropdown-item-disabled {
    pointer-events:none; //This makes it not clickable
    opacity:0.6;         //This grays it out to look disabled
}

So, Could you think about some easy posible change in RadzenDropDown to introduce this class or other solution in <li/> item generated during render?

I suggest you in past something about DisabledProperty o perhaps some posible solution with <template/>?

TIA!

Check this thread: Selectively disable items on dropdown

Hi @korchev,

Thank you, I have tried the proposal of the thread that you have recommended and it does not work. I can't avoid clicking on disabled items.

it is necessary to add "pointer-events: none" in style of generated <li/> element to work.

thank you for you support!

I was pointing you to my reply in that thread - the one saying that this isn't supported.
