I want to generate about 40 buttons on the same page, every button should be visible to only a certain group of people based on their Drupal roles.

What the best way to do it ? I thought about creating a bloc for every button but to display them with visibility restriction in the Block layout and restrict every bloc by role..but it's not very efficient and the Block layout page will be full of those blocs.

Does anyone have any suggestions ?

Thank you

you can simply create different class for each type color and based on the role you can add the class to the button.

    Hi @Gaurav, could you elaborate your answer with some snippets of code to guide OP in the right direction? At least try to provide the different hooks and theme functions. Thanks!

  • I would want to know what is your approach to create your buttons. Are you going to do it with forms?

  • It would be easier I guess with the forms because you can add your html elements such as <div class="button_1"></div> in $form['button_1']['#prefix'] and $form['button_1']['#suffix']. So now according to this class you can write css 'background-color' property for each button.
