Change display of drop down

[khemebuen]

Is it possible to change the display of the DropdownTreeviewComponent? For our project we want to only show a folder icon and when they click on the icon we show the tree. If the component used a template like the tree items do then we could change the the display to not only show text but show an icon or icon and text

Yes, you can see code to implement DropdownTreeviewComponent, it will reuse TreeviewComponent, so you will not have to write many codes.

The ngx-dropdown-treeview-select works as we would like for our project. But can we make the combo dropdown just show a folder icon not the folder selected? I extended the TreeviewComponent but the drop down does not seem to work. See attached component. Thanks

Still trying to reuse the TreeviewComponent to only how a folder icon and when the folder icon is selected the tree view shows. I setup my html for my control like this but it does not work. It just shows the whole tree and button separate. Am I missing smething:

import { Component } from '@angular/core'; import { DropdownTreeviewComponent, TreeviewI18n, TreeviewConfig } from "ngx-treeview";

@Component({ selector: 'custom-dropdown-treeview', templateUrl: './custom-dropdown-treeview.component.html', styleUrls: ['./custom-dropdown-treeview.component.scss'] }) export class CustomDropdownTreeviewComponent extends DropdownTreeviewComponent {

constructor(
    public i18n: TreeviewI18n,
    private dConfig: TreeviewConfig
) {
    super(i18n,dConfig);
}

getText(): string {
    return this.i18n.getText(this.treeviewComponent.selection);
}

onSelectedChange(values: any[]) {
    this.selectedChange.emit(values);
}

}

How to initialize the init of all as false?

I also need to customize the display of the dropdown toggle. Apart from that, DropdownTreeviewComponent fits all my needs.

Current code

https://github.com/leovo2708/ngx-treeview/blob/73698cce8f202c0cebfaee3a69467623850a46d6/src/lib/dropdown-treeview.component.html#L1-L12

Proposed Approach

The change would be very easy, I guess, by adding the possibility to inject a dropdownToggleTemplate.

This template could be provided to DropdownTreeviewComponent through an @Input(), like it is done with the headerTemplate of TreeviewComponent.

I'd like to hear your opinion about this approach before implementing...
