Investigate KSelect’s dropdown being displayed above the input in some cases even when there is enough space below
🌱 Are you new to the codebase? Welcome! Please see the contributing guidelines.
Summary
When there is enough space, KSelect's dropdown should be displayed below the input. However, there are several places in Kolibri where the dropdown is displayed above the input, even though there's enough space below. One example from Kolibri 0.17.0a0.dev0+git.123.g5cd1f6aa:
Coach → Plan → Lessons
This issue is present in other selects in Plan and Reports.
Interestingly, in a very similar place in Facility → Users, it works as expected:
The main culprit seems to be the bottom positioning set to 62px on .ui-select-dropdown. After commenting it out, the dropdown shows correctly in the Coach:
The bottom value is calculated in the calculateSpaceBelow method:
The goal of this issue is to find out why exactly the calculation doesn't work well for places in the Coach (or check whether it’s overwritten from somewhere else, even though that’s rather unlikely). After we know more, we can determine the next steps and see if the calculation can be optimized.
