Creating custom radio buttons in Angular dynamically: a step-by-step guide

I have implemented a custom radio button that works perfectly in a static environment. However, when I make it dynamic, it starts behaving like a checkbox.

<div *ngFor="let currentwork of currentworks">
    <label class="customcheck">{{currentwork}}
        <input type="radio" name="{{currentwork}}">
        <span class="checkmark"></span>
    </label>&nbsp;
</div>

When I use name={{currentwork}}, the radio buttons act like checkboxes instead. I aim to have radio buttons with only one selection possible. I am unsure why this issue is occurring and would appreciate any assistance in resolving it.

Answer №1

Ensure that the names of your radio buttons are identical.

You can use the following code snippet as an example:

<div *ngFor="let item of items">
  <label class="customcheck">{{item}}
    <input type="radio" name="items" [value]="item">
    <span class="checkmark"></span>
  </label>&nbsp;
</div>

Make sure to assign the value, not the name, for each option. The name should remain consistent across all options. Utilizing the binding bracket notation [value] is also an option instead of using value="{{}}.

<div *ngFor="let currentwork of currentworks">
  <label class="customcheck">{{currentwork}}
    <input name="myRadioButton" type="radio" [value]="currentwork">
    <span class="checkmark"></span>
  </label>&nbsp;
</div>

When using the reactive form approach, you can implement it like this -

<div *ngFor="let item of items">
  <label class="customcheck">
     <input type="radio" [value]="item.id" 
       formControlName="radiobuttoncontrolname">
     <span class="checkmark"></span>
     <span class="customcheck">{{item.Name}}</span>
  </label>
</div>

This code assumes that your 'items' are structured as follows -

items = [
 { id: 'something', Name: 'something' },
 { id: 'something2', Name: 'something2' }
];

To ensure that radio buttons function correctly, it is essential to assign them the same name attribute and provide a value for each option.

A sample implementation would look like this:

<div *ngFor="let currentSelection of selections">
    <label class="customradio">{{currentSelection}}
    <input type="radio" name="choices" value="{{currentSelection}}">
    <span class="radiomark"></span>
    </label>&nbsp;
</div>

In this example, I have used the name "choices" for all input elements with values derived from the current selection.

Feel free to check out a functional demonstration in the app.ts file.

Additional note: It is also possible to create multiple radio selections dynamically. However, you need to provide a sample showcasing your dynamic data.
