TYPO3 Core

In TCA it is possible to make form fields disappear based on the conditions of other fields (displayCond).

For this to work, you have to add a "reload" to the field it depends on so that the form will be saved and reloaded.

problems¶

• the dialog asking if one should save and reload is annoying when one is still filling out the fields
• in some cases it is unnecessarily displayed (e.g. if some fields are displayed depending on what is seletected in a list and not all changes in the list need the reload)
• the field is saved even though the editor is not done
• feels clunky and not editor friendly

Preferred change¶

Suggested alternative would be to do this behaviour in JavaScript in the core so the form is dynamically displayed.

Alternatives as developer¶

1. use displayCond and reload for the fields which should be displayed conditionally. Which means a dialog will appear on every change asking if we should continue, even for the selections where it is not relevant
2. Just show all the fields which clutters the user interface with unused options.
3. Write the code to display fields conditionally in JavaScript yourself which is extra work and makes the extensions difficult to maintain. For example if you change the field type you might have to adapt the JavaScript code.
