fxFlexOrder API in Angular flex layout

fxFlexOrder is used to order the flex children elements inside a flex container in Angular flex layout.

What is fxFlexOrder API?

  1. fxFlexOrder should be added to flex children items inside flex container.
  2. fxFlexOrder defines the positional ordering the of the elements.

We will create a component called fxFlexOrderExampleComponent in our angular project to understand it further.

fxFlexOrder example

The default order of elements inside the flex container decided based upon the position of the elements placed inside the parent container.

The default value of fxFlexOrder is ‘0’.

<h2> Without fxFlexOrder</h2>

<mat-card fxLayout>
    <mat-card class="child-1">1. Children</mat-card> 
    <mat-card class="child-2">2. Children</mat-card> 
    <mat-card class="child-3">3. Children</mat-card>
</mat-card>

Now we will define the order of children elements using fxFlexOrder.

<h2> With fxFlexOrder</h2>

<mat-card fxLayout>
    <mat-card class="child-1" fxFlexOrder="3">1. Children</mat-card> 
    <mat-card class="child-2" fxFlexOrder="2">2. Children</mat-card> 
    <mat-card class="child-3" fxFlexOrder="1">3. Children</mat-card>
</mat-card>

How fxFlexOrder will work?

If we add fxFlexOrder to the flex children, Angular flex layout will add equivalent CSS order to the flex children items.
