How to display div based on selected multiselect
I am trying to show/hide elements based on multiselect dropdown, but my code doesn't seem to work. For example, one of the data for nameList is Name, and when Name is selected, I would like to display a div with another drop-down menu. I am using Angular and Typescript. Below are my codes for your reference:
<kendo-multiselect [data]="nameList" [(ngModel)]="selectedname "></kendo-multiselect>
<div *ngIf="selectedname === 'Name'">
<div class="col-4">
You selected {{selectedname}}
</div>
<div class="col-2">Name:</div>
<div class="col-6">
<kendo-dropdownlist style="width: 100%" [data]="anotherList" [valuePrimitive]="true"></kendo-dropdownlist>
</div>
</div>

Hey, can you put theYou selected {{selectedname}}line outside the if, and just below the firstkendo-multiselectand show me the output? You are treating like theselectednamewill be a string, but I suspect its an Object since it doesnt have to store only one name.

On change event of "kendo-mutliselecet" push selectedname item to "anotherList" then set kendo-dropdownlist [(ngModel)] to this selectedname.
<div *ngIf="selectedname.indexOf('Name')>=0">
I think it will be solution. Not tested.

Basically here selectedname returns an array, so you need to check whether an item exists in an array or not. So you can use the below code to check -
<kendo-multiselect [data]="nameList" [(ngModel)]="selectedname "></kendo-multiselect>
<div *ngIf="isShown('Name')">
<div class="col-4">
You selected {{selectedname}}
</div>
<div class="col-2">Name:</div>
<div class="col-6">
<kendo-dropdownlist style="width: 100%" [data]="anotherList" [valuePrimitive]="true"></kendo-dropdownlist>
</div>
</div>
isShown(flag) {
console.log(this.selectedname.indexOf(flag));
if (this.selectedname.indexOf(flag) !== -1) {
return true;
} else {
return false;
}
}
