Hello @Orbital, welcome to the forum.
Thank you for posting your HTML. It helps people understand your description of the issue. It will be much easier to help you if you can also post your .rp file. Otherwise, we’re left to guess at how you’ve implemented this, and can’t test out and demonstrate good solutions for you, makes it hard for others to learn from this, etc.
It looks like you’ve initially set the hint property for the text field to “To”, but when ‘X’ is clicked, you then set the text to “To” instead of “” (blank). A little hard to tell because the styling of the hint text and entered text is the same (poor usability), but if the text value of the input field were indeed blank (thus automatically triggering the hint text to show) then entering any text would clear the hint, instead of beginning the text entry with “To”. This is something you should fix, but even so, this is not likely the root of your issue because backspacing to clear “To” and entering “g” should show your autofill dropdown menu.
My guess is that you need to fix the logic for your conditional case on the “To” text field. I notice that even if I don’t click the ‘X’ the dropdown is never shown a second time. For example, if I enter “z” the dropdown shows with one entry (Glazebrook); I select that entry and the text field value gets set to “Glazebrook” and the dropdown hides; If I then backspace to delete all text and enter “z” (or “g” or any char) nothing happens.
So, what are the exact conditions you have set for showing the dropdown? Is it via OnTextChange or OnKeyUp? (The latter should be more reliable.) If it is a “Show, slide down” does it also include the checkbox option to “Bring to front”? Try that. If your dropdown is a dynamic panel and changes states when shown/hidden, be sure that the dp is changed back to its initial state when hiding the dropdown.
Or, perhaps you are inadvertently causing a bug when you hide the dropdown. Does it get sent to back? If so, be sure to “bring to front” when it is shown (or state changes) by selecting that checkbox option (under MORE OPTIONS in the action details.)
