This property specifies whether HTML format should be enabled for the text of the popup menu. For example, an item with HTML enabled that has its text as <b>Test will result in a bold Test. Note that if you have HTML enabled and that user selects the <b>Test item, the event will only give you Test as the item selected.

Accepts: boolean

:bookmark: Why this extension?

As you know, we have a lot of popup menu extensions currently available.

However, what's special about this extension is that you can enable/disable HTML for your popup texts, so you can not just set the color of the text, but also size, strikethrough, bold, underline, italic, etc. This extension also has ID support, so you can create 2+ menus with the same extension!

I have used that extension for some time, and took that extension as reference. That extension does have a lot of functions that this one, unfortunately, that extension does not have the function to detect whether the user has dismissed the popup (when it is necessary), nor it has functions to set the gravity.

Glad to see your additional features you provided for a popup menu. Both you and Ulli share valuable open source extensions from which extension developers can learn. App Inventor is a learning tool.

There are many ways to code a Procedure with Blocks. Often community members post alternate code that produces a similar result. Anyone is free to chose the solution that works best for them for a Block algorithm or extension :slight_smile: .

Strange that you did not reference it in your original post then ?

these options doesn't seems to be working for me. please help what can I do

The gravity also depends on your button location. For example, if your button is at the bottom of the screen, even though if you set AlignVertical to Bottom, the popup may still show above the button. For HtmlFormat, you cannot use tags like <p style="font-size:30px">. Remember: you have to set the properties before you show the menu.

Also is there any way to set it to dark theme? can you make another extension just like you gave me one for daffy dialog??

Can you try that extension I sent you earlier?

I tried it just now it isn't allowing me to use text to set dark or light how should I use it??

Edit: No need I decided to use timai's extension it's just amazing.

Hmmm...can you show your blocks? It is working fine for me here.

There's one cool thing that in one ui this type of dialogs are on title bar only in others and in stock android this popup comes a bit down.
Here you go:

One Ui

Stock Android 12

In a PM you asked me what is gravity. Gravity is the location of the popup. For example, if you have set AlignVertical to Bottom, the popup will show below the button. However, if you have the button at the very low position of the screen, it still may not show the gravity as bottom.

but gravity doesn't even works on a12 and in one ui also it looks same.

As I said, there is no gravity the popup will show exactly where you want. The system will also decide automatically.
