Is it possible to have isometric view in Tilesets window? Unity has isometric view in Tile Palette window which is the correct view for isometric tilesets.
No.
There is a planned “scratch pad” panel which will let you put your tiles into a map with any orientation and arrangement you like, and pick from it as if it were a tileset, but I don’t know when we’ll get that: Scratch pad map panel · Issue #3288 · mapeditor/tiled · GitHub
For now, you can at least increase how many tiles you see per row, either by enabling dynamic wrapping on the tileset, or increasing its column count (if it’s an Image Collection). I don’t see the dynamic wrapping button in your screenshot though, are you using a very old version of Tiled? You also have some extra buttons in the tileset panel, is this a fork of Tiled rather than the regular Tiled?
Thank you for your answer. I was posting from my phone, so i download the image from Google just as an example.
