To hide a gallery with a blue button in Power Apps, you can use the visibility property of the gallery and a variable to toggle this property when the button is clicked. Please explain your use case in more detail.

Hi @sabrinaaa_ , As per my understanding, you want to hide your gallery once the up and down arrow is pressed in your gallery header for project details. Here's how you can do it:

// On click of the upside arrow, on select declare variable
UpdateContext({VarProjectdetails: !VarProjectdetails})

// Then take the gallery and header in a data card if it's a scrollable screen or if not, take it in a vertical container
// Set the vertical container height
If(VarProjectdetails, galleryheight + headerheight, headerheight)

// Likewise, on the gallery visible property just place VarProjectdetails
Gallery.Visible = VarProjectdetails

This should solve your problem. Do let me know if you need additional help or please accept my answer as a solution.

Please replace `'galleryheight'` and `'headerheight'` with the actual height of your gallery and header.
The `!VarProjectdetails` is used to toggle the visibility of the gallery. When the up arrow is clicked, the `VarProjectdetails` variable is toggled, which in turn toggles the visibility of the gallery. If the gallery is currently visible, it will be hidden, and vice versa. The `If` function is used to set the height of the container based on the visibility of the gallery. If the gallery is visible, the height of the container is set to the sum of the gallery height and the header height. If the gallery is hidden, the height of the container is set to the header height. The `Gallery.Visible` property is then set to the value of the `VarProjectdetails` variable, which determines whether the gallery is visible or not.  please let me know if any additinal details required or accept my solution as answer to your question
