How to show tooltip on @ng-select/ng-select options

ng-select option title
select option hover tooltip
mat-option tooltip
ng-select selected value
ngbtooltip
ng-select clear
ng select pagination
ng-bootstrap select

I am using @ng-select/ng-select@2.3.6 in my application and i have a very long text in array.

So, the complete text not visible in dropdown list so I want to show the title/ tooltip over the each and every options

I tried,

let listArray = [{name: 'Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s'}];

<ng-select placeholder="Select" (change)="onChange($event)">
      <ng-option *ngFor="let list of listArray" 
       title="{{list.name}}"> {{list.name}} </ng-option>
 </ng-select>

But no luck

you can achieve tooltip solution using below code

<ng-select [items]="listArray" bindLabel="name" bindValue="name">
    <ng-template ng-option-tmp let-item="item">
    <div title="{{item.name}}">{{item.name}}</div>
    </ng-template>
</ng-select>

Thanks

You can use @ng-bootstrap/ng-bootstrap library to display a tooltip in parallel with ng-select:

template:

<ng-select [ngbTooltip]="tipContent" container="body" placement="bottom" placeholder="Select" (change)="onChange($event)">
      <ng-option *ngFor="let list of listArray" title="{{list.name}}"> {{list.name}}  
     </ng-option>
</ng-select>

<ng-template #tipContent>{{listArray[0].name}}</ng-template>

ts:

listArray = [
    {name: "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s"}
];

Demo

I added a demo using only bootstrap with no external libraries. Hover on the options to see the tooltip (takes a couple of seconds until it is displayed): New Demo

ng-select/ng-select, I need to see the title for the selected option, because usually the text is from the list to see the tooltip while mouse is over the ng-select input. <select data-ng-model="mySelections[0].SearchFilterMembershipsScope" data-ng-options="i.id as i.name for i in searchscope" data-ng-required="true"></select> I have successfully generated a select with the 3 options. What would be the best angular way to display a tooltip of the currently selected items "description"?

You can put a template inside the <ng-option>, and add the directive ng-option-tmp:

<ng-select [items]="listArrayManyElements" placeholder="Select" [(ngModel)]="Selected" 
           bindLabel="name" bindValue="name">
    <ng-template ng-option-tmp let-item="item">
        <div [title]="item.name">{{item.name}}</div>
    </ng-template>
</ng-select>

How to show tooltip on @ng-select/ng-select options, I am using @ng-select/ng-select@2.3.6 in my application and i have a very long text in array. So, the complete text not visible in dropdown list so I  I am using ng-options for dropdown using 'select' tag. I have to select only one option from drop down at a time. While selecting option from drop down I have to show tooltip when I am hovering mouse on particular option. I am able to show all the values in dropdown but not able to show the tooltip.

You can create custom directive like that:

import { ContentChild, Directive, ElementRef, OnInit } from '@angular/core';
import { NgSelectComponent } from "@ng-select/ng-select";

@Directive({
selector: '[admSelectTitle]'
})

export class SelectTitleDirective implements OnInit {

@ContentChild(NgSelectComponent) select: NgSelectComponent;

@ContentChild(NgSelectComponent, { read: ElementRef }) selectNative: ElementRef;

/**
 * @inheritDoc
 */
ngOnInit() {
    if (!this.select) {
        return;
    }
    const nativeElement = this.selectNative.nativeElement;
    nativeElement.addEventListener("mouseover", function() {
        const listOfPickedElements = nativeElement.querySelectorAll('.ng-value-label.ng-star-inserted');
        listOfPickedElements.forEach((el) => {
            el.setAttribute('title', el.innerHTML);
        })

        const listOfAvailableOptions = nativeElement.querySelectorAll('.ng-dropdown-panel-items.scroll-host .ng-option.ng-option-marked');
        listOfAvailableOptions.forEach((v) => {
            v.setAttribute('title', v.innerText)
        })

    })
}
}

After that you can simply use it:

<ng-select admSelectTitle [items]="yourItems" bindLabel="name" bindValue="id" class="anyClass" formControlName="anyName" [multiple]="true">
                    <ng-template ng-option-tmp let-item="item">
                        {{ item.name }}
                    </ng-template>
                </ng-select>

now there are tooltips on ng-select and on ng-options elements. Sorry for bad English=)

How can I Apply title/ tooltip / popover on options of select by using , The ng-options directive fills a <select> element with <options>. The ng-options directive uses an array to fill the dropdown list. In many cases it would be easier to  This seems to be a more obvious way of defaulting a selected value on an <select> with ng-options.

Angular ng-options Directive, Bootstrap widgets for Angular: autocomplete, accordion, alert, carousel, Tooltips can contain any arbitrary HTML, Angular bindings and even directives! This option is useful if the element triggering the tooltip is inside an element that clips  It seems in the 2 years since this was asked, the other browsers have caught up (at least on Windows not sure about others). You can set a "title" attribute on the option tag: <option value="" title="Tooltip">Some option</option> This worked in Chrome 20, IE 9 (and its 8 & 7 modes), Firefox 3.6, RockMelt 16 (Chromium based) all on Windows 7

Comments
  • Well, it's probable that there is a max-length. Shorten your text for testing purposes to 1 word and have a look whether this works at least.
  • I have shorten text as well but issue still exist.
  • I don't have a single value in array, Having up to 15 objects so, In this case how it will work.
  • I added a demo using only bootstrap with no external libraries to meet your requirements. Don't know if it is ok for you but take a look in case you want to try it. Using ng-select is a bit tricky when you have multiple items to display a tooltip.
  • Thanks for the answer but bootstrap dropdown looking very bad. I don't want to use that.
  • "<div [title]="list.name">{{list.name}}</div>" it consider as a options value and div also printed in the list.
  • @AniketAvhad I've updated my answer, you have to bind a value to the ng-option
  • If i use your solution then problem like this, please have a look into stackblitz.com/edit/…"
  • @AniketAvhad I've browsed a bit through the source code, and you should use the ng-option-tmp directive
