Conceal the text within a specific section of the select element

Question

Conceal the text within a specific section of the select element

In my sidebar, there is a select element. When the sidebar collapses, all elements are replaced with icons. I want the select to only display the arrow button at that point while maintaining a minimum width and avoiding any unnecessary white space around it. Is there a way to achieve this without hiding the button completely?

Markup:

<select [ngClass]="{'account-selector': !sidebarCollapsed, 'account-selector-collapsed': sidebarCollapsed}" [(ngModel)]="selectedAccount" (change)="setSelectedAccount()">
    <option *ngFor="let account of accounts" [ngValue]="account" [selected]="account === selectedAccount">{{account.data.Name}}</option>
</select>

CSS:

.account-selector {
    max-width: 90%;
}

.account-selector-collapsed {
    // What should be included here?
}

html css angular html-select

Successfully implemented the solution using the following CSS:

.account-selector-collapsed {
    cursor: pointer;
    width: 15px;
    height: 15px;
    font-size: 0; // hiding text for current selection
    border: 0;
    background: white; // TODO: replace with appropriate image
    -moz-appearance: none;
    -webkit-appearance: none;
}
.account-selector-collapsed::-ms-expand {
    display: none;
}

The key component is -moz/webkit-appearance: none;, which transforms it into a plain text box that can be customized freely, while ::-ms-expand has a similar function in IE/Edge. I have not had extensive testing on the latter (running on a Mac and my Windows VM is having issues), but based on preliminary tests, it seems to be functional on those platforms as well as other browsers.

Without access to the plunker for observation, my best assumption is that you may need to modify your CSS as follows:

.account-selector-collapsed {
    width: calc( 80% - 20px) /*adjust the value of 20px based on your requirements*/
}

After spending a considerable amount of time attempting to style the select element, it became clear that achieving consistent styling across browsers is currently unattainable. Each browser has its unique way of rendering the native select box element, even when styled with css.

Given that you are utilizing Angular 4 (2), creating your custom select using just a <div> or any desired element is rather straightforward.

Here is an example implementation:

select.component.html:

    <div class="select-options">
      <div
        class="select-option"
        *ngFor="let option of options"
        [attr.data-value]="option.id"
        [class.selected]="option.active"
        [innerText]="option.title"
        (click)="selectOption(option.id);"
      >
      </div>
    </div>

select.component.ts:

import { Component, OnInit, Input } from '@angular/core';

@Component({
  selector: 'app-select',
  templateUrl: './select.component.html',
  styleUrls: ['./select.component.scss']
})
export class SelectComponent implements OnInit {
  @Input() options: Array<any> = [];

  constructor() {}

  ngOnInit() {

  }

  selectOption(optionId) {
    this.options.map(option => period.active = option.id === optionId);
  }
}
