Problem
You want to allow users to enter information into the application.
Forces: factors that affect selection
- There may not be much space. Forms elements are typically verbose and forms require at least a submit button.
Solution
Moodle uses progressive disclosure to hide form items that are suspected to be needed a minority of users.
On simple forms, (less than one page / four elements or less) autofocus the first field of the form on body onload
- IF none of the fields have any changed content in them (i.e. if the user is not returning to the page from browser history, see: [https://tracker.moodle.org/browse/MDL-825 MDL-825])
Date selection: use javascript selector (how about time?)
- Show the more important settings at the top
- Each entry should have a label, and if necessary, a help file
- If there are more than 10 options, split them into required and optional/extra/advanced parameters
Common mistakes
Autofocusing a field by default is an accessibility issue, see MDL-20410

- TODO: Inconsistency with buttons in each module configuration: save and return to course / save and display / cancel. Are there really use cases to support having this choice each time?
