In a recent thread I suggested including Type in the list of Dynamic Attributes for input. I think it would also be useful to have Placeholder added. In fact, there is probably a case for making any attribute dynamic and available in the UI.
This is obviously not an important request; it is straightforward to add this to the code manually. However, having it included in the UI confirms that it’s an option and will work - and saves a few keystrokes.
I added quite a number of these a few days ago and now I see the new attribute and value in the Properties panel. It’s not only useful for adding and selecting attributes and their values - it’s also useful for seeing the applied properties at a glance, and for copying/pasting values in some cases (I was adding placeholder expressions for multi-lingual inputs). These little tweaks help to make the Wappler UI such a pleasure to work with.
