Hi does anyone know how to make clear colour settings with the blocks in ios. Alternatively another way to make buttons on a screen disappear completely after use?

Hi @badbrains, it depends on which component you are working with, but anywhere you see a “Colour” property you should be able to adjust it’s opacity (also known as alpha value or alpha channel)

Hi. Appreciate you getting back to me. I need to use blocks so the button text and background will be transparent(disappear) after click but in the colour block there doesn’t seem to be a way to enter an alpha value? Thanks a lot 🙂

Hi,

It does not work like that from BLOCKS!

The color pallet presented from BLOCKS only have the colors available:

There is no option form setting opacity or alpha.

I need this feature too
