Add the ability to define custom options for the 'Main focus' and 'Category' fields when creating a simulation #3583
Description
Context
This feature is needed to make the simulation creation process more flexible and adaptable to different use cases. Currently, the "Main focus" and "Category" fields are limited to predefined options, which may not cover all the specific needs of users or projects.
Current Workaround
For the moment, I haven't found any workaround, so I have no choice but to use the existing options in the dropdown menus.
Proposed Solution
To solve this issue, you could implement one of the following approaches:
-Make the "Main focus" and "Category" fields directly editable, allowing users to type in custom values.
-Alternatively, provide an option to add new entries to the existing lists, so users can extend the predefined options with their own.
