What It Does

Joomla Component Builder (JCB) gives you fine-grained control over how each field behaves depending on where it’s rendered:

• List View (e.g., admin list of items)
• Edit View (e.g., form used to create/edit an item)

Every field in JCB has separate configurations that let you control:

• Whether it should appear in the list or form (or both)
• Custom column title for list view
• Column width, alignment, and ordering
• Field label, tooltip, and description
• Default values for new records
• Conditional rendering or JavaScript visibility rules

Where to Configure It

Inside the Field entity GUI, you’ll find:

• ✔ Show in List
• ✔ Show in Form
• Field Label
• Field Description
• List Column Width
• List Column Class (for styling)
• Placeholder text (form only)
• Tab/Accordion grouping options (form only)

Use Cases

• Show a "status" field in the list view as a colored badge, but disable editing in the form.
• Hide internal or computed fields from the form but show them in the list as read-only.
• Reformat dates, prices, or booleans differently in list vs form using custom render layouts or field templates.
• Group fields visually into tabs or sections in the edit form while maintaining a clean list view.

Benefits

• ✅ Decouples list layout from form layout
• ✅ Reduces form clutter for complex records
• ✅ Makes admin list views cleaner and more informative
• ✅ Allows read-only fields in lists without enabling editing
• ✅ Enables logic-based display using JavaScript callbacks

Conclusion

Per-display rendering configuration makes your components more usable, by ensuring that each field only appears where it’s truly relevant — and always in the most effective layout. JCB empowers you to shape the admin experience with intention, clarity, and precision.
