OMG wow, yes, that resolved the issue. Thank you for your swift response, it's greatly appreciated 🙂
To improve UX, please consider adding a pointer cursor when the user hovers over a row.
I never considered clicking the empty area of the row to open a drop-down. I also move the cursor too fast to see the helper text. Even the subtle hover state didn't alert my brain to that functionality.
I would typically click a title link to open an item if there is no pointer cursor. Or identify a drop-down by an > arrow icon or similar to alert me to the drop-down functionality.
