CSS - How to increase width of the dropdown using CSS?

Question

In the code I have checkbox, when checked the dropdown is displayed. If 1st value of dropdown is selected the next dropdown is displayed next to it. The problem is I am unable to increase the width of the dropdown and the full text is not visible.

   <div class="flex items-center w-full">
                        <div id="data" fxLayout="row" class="w-1/3">
                            <mat-checkbox formControlName="allowData"
                                >Allow</mat-checkbox
                            >
                        </div>
                        <div
                            *ngIf="form2.value.extendedProperties.allowData"
                            fxLayout="row"
                            fxLayoutAlign="start center"
                            fxLayoutGap="16px"
                            class="w-1/4"
                        >
                            <mat-form-field>
                                <mat-select
                                    placeholder="Amazon"
                                    formControlName="dataCharged"
                                >
                                    <mat-option
                                        *ngFor="let info of dataCharged.values"
                                        [value]="info"
                                        >{{ dataCharged.descriptions[info] }}</mat-option

                                </mat-select>
                            </mat-form-field>

                            <mat-form-field

                        </div>

Answer 1

The w-full class will make the inner element take up the full width of its parent, regardless of the parent's width.

Here's an example:

<div class="w-2/5">
  <div class="w-full">
    <!-- Content inside div with full width -->
  </div>
</div>

In this example, the outer div has a width of 2/5 of its parent, and the inner div will take the full width of the outer div due to the application of w-full. This allows the content inside the inner div to stretch across the entire width of its containing block. Adjust these classes based on your specific layout requirements.
