Enhancing PrimeNG Components with Custom CSS Styles

I have embarked on a project to develop a sleek user interface utilizing Angular 4, Angular Materials, and PrimeNG components.

The most recent challenge I am facing involves the MultiSelect Component from PrimeNG: https://www.primefaces.org/primeng/#/multiselect

My goal is to ensure that the width of the component stretches to 100% of its parent container.

Is there a specific procedure I should adhere to in order to modify CSS classes for this particular component? The documentation mentions using "Style" for inline styling - does this mean:

<p-multiSelect [options]="cars" [(ngModel)]="selectedCars" [defaultLabel]="defaultLabel" style="width: 100%;"></p-multiSelect>

Despite following these steps, I have not been able to achieve the desired outcome.

Furthermore, the documentation suggests using "styleClass" as a property to apply a custom CSS class. How can I implement this?

Lastly, a list of CSS classes utilized by the PrimeNG component is provided on their website (e.g. ui-multiselect). I have attempted to override 'ui-multiselect' by defining it in the Angular component's CSS file, but my changes do not reflect.

Any suggestions or insights on what I might be overlooking?

Answer №1

If you want to customize the styling of PrimeNG components inline, you can do so like this:

[style]="{'width': '100%'}"

To apply a specific CSS class using styleClass, simply include it like this:

styleClass="example-css-class"

This allows you to customize the appearance of components like multi select input fields by applying various style classes, such as Bootstrap's form-control.

When working with PrimeNG components, it's recommended to place styles in component-specific .css files. If you prefer to use a global stylesheet like styles.css, you may need to override PrimeNG styles by configuring the .angular-cli.json file. You can achieve this by adjusting the styles array like so:

"../node_modules/primeng/resources/primeng.min.css",
"../node_modules/primeng/resources/themes/omega/theme.css",
"styles.css"

By placing your styles.css after the PrimeNG resources, it will be loaded last and take precedence over PrimeNG's default styles.
