I want to create a big table, lots of rows(about 150~ rows). Is it a good idea to use Repeater Field? Performance wise and UX wise.
How much rows are too much rows for a repeater field?
I wouldn’t think so. If you want to make a table, a traditional table plugin would be a better solution as it will end up being more user friendly and easier to work with than an extremely large repeater field. Try one of the below plugins or check the WordPress repository:
TablePress
Advanced Custom Fields: Table Field Plugin
All being said it’s just my opinion.
