Hi Mavis, Intuiting the sweet spots to drag and drop custom parameters on forms takes some practice, so to help you build up the right muscle memories, here are a few tips:
click an existing parameter first, then add the nee parameter to have it inserted immediately following the existing parameter
drag and drop a parameter to the right of another parameter to have both enclosed in a rectangle, confirming that they will be presented on the same line within the custom form (providing there is sufficient horizontal space to do so; otherwise, browser wrapping will occur)
to break a parameter onto its own line, drag it out (typically below) of the containing rectangle...or in a pinch (if that’s too irksome), remove it, the (BEFORE applying or saving the form, lest yee lose yer data) the re-add it in the new location
consider using parameter sections on a custom form for logical separation, easier drag and drop by section maintenance, and (optionally) to set security restrictions by section (NOTE: be aware that such security setting sometimes "leak" onto following sections, so as a general best practice, it is prudent to locate such security-sensitive sections at the bottom of the form)
to reduce scrolling when dragging a parameter or section a long distance on a form, consider clicking the item in question, zooming your browser out a ridiculous amount (eg 25% using [ctrl]+[-]), dragging as needed to get it close, then zooming in (using [ctrl]+[+]) to drag it to the desired location
when making major revisions to a form, consider copying the form, getting it Just So, adding it (via bulk edit) to EVERY item with the existing custom form (lest yee lose yer data), inspect to confirm the new fotm looks good and is populated, then and ONLY then delete the original form, and (finally) rename the copy back to the original name
Back in the day, before the maximum 500 parameter cap per form was introduced (in no small part due to yours truly), I regularly maintained custom forms with 1700+ parameters across our multiple (Oil & Gas) clients. Even with the tricks above, doing so manually became so tedious, time consuming, and challenging that we developed (and in due course, made available to the public) our "https://store.atappstore.com/product/populate-category-generator/" Update Category Generator and "https://store.atappstore.com/product/populate-category/" Update Category solutions, which allow you to export, then manipulate and update (respectively) a form's definition using Excel (SO much easier), including formulas, but excluding form logic. Whichever path you choose, Happy Trails...and do watch your step. Regards, Doug Doug Den Hoed - AtAppStore
