You can create client scripts to customize the catalog.

## Vorbereitungen

Role required: admin

## Warum und wann dieser Vorgang ausgeführt wird

Use catalog client scripts to control the behavior of the catalog items
when presented to your users. Catalog client scripts can be applied to a catalog
item or a variable set. These scripts run on the browser instead of the server,
allowing you to better control the information that the user submits.  
The priority order for g_form APIs is:

1. Mandatory (highest)
2. ReadOnly/Display
{#t_CreateACatalogClientScript__ol_lvz_g3z_sbb}

If a variable is set to mandatory and doesn't have a value, readonly or hide doesn't work on that variable. If a variable is hidden or readonly, and then set to mandatory, the variable field becomes visible or editable.

This priority order is also applicable for variable sets and containers. If a variable set or container has a mandatory variable without any value, then the container or variable set can't be hidden.
