Angular Bootstrap inputs

MDB provides several form control styles, layout options, and custom components for creating a wide variety of forms.

All of them are created in beautiful, material design style.

MDB Angular supports the following types of inputs: button, checkbox, email, file, hidden, number, password, radio, range, reset, search, submit, tel, text, textarea.

Input fields

Basic example 



<div class="md-form">
    <input mdbInputDirective type="text" id="form1" class="form-control">
    <label for="form1" class="">Example label</label>
</div>

Two-way data binding

Look at me: 


<div class="md-form">
    <input mdbInputDirective type="text" name="text" [(ngModel)]="text" id="form1" class="form-control">
    <label for="form1" class="">Example label</label>
    <p>Look at me! {{text}}</p>
</div>


import { Component } from '@angular/core';

@Component({
    selector: 'two-way-component',
    templateUrl: './two-way.component.html',
    styleUrls: ['./two-way.component.scss']
})
export class TwoWayComponent {
    text: string;
}

Small input 


<div class="md-form form-sm">
    <input mdbInputDirective type="text" id="form1" class="form-control form-control-sm">
    <label for="form1" class="">Example label</label>
</div>

Icon Prefixes 


<div class="md-form">
    <i class="fa fa-envelope prefix"></i>
    <input mdbInputDirective type="text" id="form2" class="form-control">
    <label for="form2">Example label</label>
</div>

Placeholder 


<div class="md-form">
    <input mdbInputDirective placeholder="Placeholder" type="text" id="form58" class="form-control">
    <label for="form58">Example label</label>
</div>

Prefilling Text Inputs 


<div class="md-form">
    <input value="John Doe" type="text" id="form6" class="form-control" mdbInputDirective>
    <label for="form6">Example label</label>
</div>

Error or Success Messages


There are available such fields as minLength, maxLength, data-error and data-success.

minLength, maxLength defines minimum and maximum input length. data-error, data-success provides space to enter your's custom error or success message


Validation options


You can validate inputs with types: text, email, password. Please notice, that for proper validation works, mdbInputDirective directive is obligatory.



                               
<form>
  <div class="md-form">
    <i class="fa fa-envelope prefix"></i>
    <input mdbInputDirective data-error="wrong email" data-success="valid email" minLength="8" maxLength="25" type="email" class="form-control" id="form9" name="email" mdbInputDirective>
    <label for="form9">Type your e-mail</label>
  </div>

  <div class="md-form">
    <i class="fa fa-lock prefix"></i>
    <input mdbInputDirective data-error="wrong password" data-success="valid password" minLength="10" maxLength="25" type="password" class="form-control" id="form10" name="password">
    <label for="form10">Type your password</label>
  </div>
</form>

Disabled input

Add the disabled boolean attribute on an input to prevent user interactions.

To use not-allowed cursor add .disabled class to the label.


<div class="md-form form-sm">
    <input type="text" id="form11" class="form-control" disabled>
    <label for="form11" class="disabled">Example label</label>
</div>

Form layouts

Since Bootstrap applies display: block and width: 100% to almost all our form controls, forms will by default stack vertically. Additional classes can be used to vary this layout on a per-form basis.

Inline forms:

Use the .form-inline class to display a series of labels, form controls, and buttons on a single horizontal row. Form controls within inline forms behave differently:

  • Controls are display: inline-block to provide alignment control via vertical-align and margin.
  • Controls receive width: auto to override the Bootstrap default width: 100%.
  • Controls only appear inline in viewports that are at least 768px wide to account for narrow viewports on mobile devices.

Because of this, you may need to address the width and alignment of individual form controls manually. Lastly, as shown below, you should always include a <label> with each form control.

Login 

<form class="form-inline">

    <div class="md-form form-group">
        <i class="fa fa-envelope prefix"></i>
        <input mdbInputDirective type="email" class="form-control" id="form9" name="email">
        <label for="form9">Type your e-mail</label>
    </div>
    <div class="md-form form-group">
        <i class="fa fa-lock prefix"></i>
        <input mdbInputDirective type="password" class="form-control" id="form10" name="password">
        <label for="form10">Type your password</label>
    </div>

    <div class="md-form form-group">
        <a class="btn btn-primary btn-lg waves-light" mdbWavesEffect>Login</a>
    </div>

</form>

Using the Grid

For more structured form layouts, you can utilize Bootstrap’s predefined grid classes (or mixins). Add the .row class to form groups and use the .col-* classes to specify the width of your labels and controls.


<form>
    <!--First row-->
    <div class="row">
        <!--First column-->

</form>

import { Component, ElementRef, Renderer2, ViewChild } from '@angular/core';

@Component({
  selector: 'range-example',
  templateUrl: 'range.html',
})

export class RangeComponent {
    @ViewChild('input') input: ElementRef;
    @ViewChild('rangeCloud') rangeCloud: ElementRef;
    range: any = 50;

    constructor(private renderer: Renderer2) { }

    coverage() {
    if (typeof this.range === "string" && this.range.length !== 0) {

      return this.range;
    }
    const maxValue = this.input.nativeElement.getAttribute('max');
    const cloudRange = (this.range / maxValue) * 100;
    this.renderer.setStyle(this.rangeCloud.nativeElement, 'left', cloudRange + '%')
  }
  
}

Character counter MDB Pro component

Use a character counter in fields where a character restriction is in place.
