Disable a checkbox in ColumnMenuChooser component

[Kate]

Hello, 
I'm using Kendo UI Grid for Angular. I'm using the ColumnMenuChooser component in two places in my code.
In one place, I'm using just the generic directive :

<kendo-grid-columnmenu-chooser [service]="service">
</kendo-grid-columnmenu-chooser>

In another place, I'm using a more customized code :

<ng-template #template>
<kendo-grid-columnlist
[columns]="columns"
[applyText]="localization.get('columnsApply')"
[resetText]="localization.get('columnsReset')"
[autoSync]="autoSync"
[allowHideAll]="allowHideAll"
(apply)="onApply($event)"
(columnChange)="onChange($event)"
>
</kendo-grid-columnlist>
</ng-template>

In both places, is it possible to disable a column's checkbox according to its column's property ?
I know this was possible in Kendo UI grid for jQuery but I can't find a way to do it in Kendo UI for Angular.
The goal is that if a given column has a certain property true (for example "locked = true", then it would be impossible for the end user to hide it via the ColumnMenuChooser component.
Thank you in advance

If there are no other choice, I'm thinking about using the 'includeInChooser' input, which will remove completely the column from the chooser.

Is there a way to just disable the checkbox instead of removing the column ?

Hi Kate,

It looks like the kendo-grid-columnlist component is custom. I am not sure what its content is, but it looks like it is used in such way that a generic input of type checkbox is rendered for each of the columns array items passed to it.  If that is the case, then this approach will allow you to control the state of the input through its generic [disabled] input property.

About the ColumnMenuChooser component, it doesn't currently provide the required functionality as a built in feature. 

The includeInChooser option could definitely be used to control which columns are added to the ColumnMenuChooser.
