Select
Dropdown
The dropdown component uses the HTML select element and adds custom styling and additional functionality.
Basic usage
<mbsc-dropdown label="Choose one">
<option>Option 1</option>
<option>Option 2</option>
<option>Option 3</option>
</mbsc-dropdown>
<mbsc-dropdown label="Choose one">
<option *ngFor="let opt of myOptions" [value]="opt.value" >{{opt.text}}</option>
</mbsc-dropdown>
Value binding
The dropdown can be bound to a string value using either the [(ngModel)]
or the formControlName
directives.
In this case the dropdown will update it's state according to the bound value.
<mbsc-dropdown [(ngModel)]="myValue" label="Choose one">
<option value="opt1">Option 1</option>
<option value="opt2">Option 2</option>
<option value="opt3">Option 3</option>
</mbsc-dropdown>
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
templateUrl: './app.component.html'
})
export class MyComponent {
myValue = '';
}

Customizing the appearance
While the provided pre-built themes are enough in many use cases, most of the times on top of adapting to a specific platform, you'd also like to match a brand or color scheme. Mobiscroll provides various ways to achieve this:
- Create custom themes using the theme builder - the custom themes can be also built using out theme builder, on a graphical user interface, without any coding, or the need for Sass support in your project.
- Create custom themes using Sass - use this, if you need multiple themes with different color variatons, in case you have pages with different colors, or you'd like to users to customize the colors of your app.
- Override the Sass color variables - the straightforward way to change the colors in one place throughout the application.
Override the Sass Color Variables
A convenient way to customize the colors of the Mobiscroll components is to override the Sass color variables.
Let's say your branding uses a nice red accent color, and you'd like that color to appear on the Mobiscroll components as well,
while still using platform specific themes (e.g. ios
on iOS devices, material
on Android devices, and mobiscroll
on desktop).
You can override the accent color for every theme:
$mbsc-ios-accent: #e61d2a;
$mbsc-material-accent: #e61d2a;
$mbsc-mobiscroll-accent: #e61d2a;
@import "~@mobiscroll/Angular/dist/css/mobiscroll.angular.scss"
You can also customize the colors on many levels:
- Theme specific variables (ex.
$mbsc-material-background
,$mbsc-ios-dark-text
) are applied to all components in a theme. Complete list of variables here. - Component specific global variables (ex.
$mbsc-card-background-light
,$mbsc-listview-text-dark
) are applied to all themes for a specific component. - Component and theme specific variables (ex.
$mbsc-ios-dark-form-background
,$mbsc-material-input-text
) are applied to a specific theme and a specific component.
Tree Shaking for styles
Tree shaking is a term commonly used in web development and particularly in JavaScript for unused code removal. Since websites are served (mostly) over the network, loading times depend on content size, so minification and unused content elimination plays a major role in making webapps fluid.
For the JavaScript part, popular frameworks already have the treeshaking built in, so the components that are not used will be left out from the built project.
Eliminating unused styles
In case of the styles, leaving out the unused rules is not as straight forward.
The overarching idea is that CSS selectors match elements in the DOM, and those elements in the DOM come from all sorts of places:
your static templates, dynamic templates based on server-side state, and of course, JavaScript, which can manipulate the DOM in
any way at all, including pull things from APIs and third parties.
Sass variables to the rescue
The Mobiscroll Library comes with a modular SASS bundle, that can be configured which component styles and which themes to leave in and out for the compiled css file.
Every component and theme has a SASS variable that can be turned on or off. If the variable is falsy the styles that it needs will not be added to the bundle.
// include the ios theme
$mbsc-ios-theme: true;
// include the components:
$mbsc-datepicker: true;
$mbsc-eventcalendar: true;
@import "@mobiscroll/angular/dist/css/mobiscroll.modular.scss"
In the above example the styles needed for the eventcalendar and datepicker will be included and only for the ios theme. All other components (like select or grid-layout) and all other themes will be left out from the bundle.
Here's the complete list of the components and themes that can be used:
$mbsc-datepicker
$mbsc-eventcalendar
$mbsc-forms
$mbsc-grid-layout
$mbsc-popup
$mbsc-select
$mbsc-ios-theme
$mbsc-material-theme
$mbsc-windows-theme
For example if you don't want to include the form components (input, button, segmented, etc...), but you are using the select component, the styles for the mobiscroll buttons, will still be in, because of the dependency.
