Image Select

Hi all. Can you help me. I'm trying to make an image selector, like the one made here by https://github.com/jrieke/streamlit-image-select for streamlit. I tried to do this using ToggleButtonsSingle, it worked for me, but all the buttons with pictures end up in one line, and I can have a lot of pictures, I tried to add GridFixed, but now everything crashes because it can’t find the value correctly.

Hi @icecream4! I think this should work for you:

...
selected_image = solara.reactive(0)

@solara.component
def Page():
    with solara.GridFixed(columns=3):
        for i, url in enumerate(images):
            def set_print(value = i):
                print("Image", value)
                selected_image.set(value)

            with solara.Button(on_click=set_print, style={"height": "150px", "width": "150px"}):
                solara.v.Img(src=url, height="150px", width="150px", contain=True, aspect_ratio="1/1", style_="border:" + "1px solid red" if selected_image.value == i else "1px solid black")

...
selected_image = solara.reactive(0)

@solara.component
def Page():
    with solara.GridFixed(columns=3):
        for i, url in enumerate(images):
            def set_print(value = i):
                print("Image", value)
                selected_image.set(value)

            with solara.Button(on_click=set_print, style={"height": "150px", "width": "150px"}):
                solara.v.Img(src=url, height="150px", width="150px", contain=True, aspect_ratio="1/1", style_="border:" + "1px solid red" if selected_image.value == i else "1px solid black")

I think the reason your original code didn't work is in the for loop; the value of i changes as we loop through, and the last reference ends up in the value of all buttons.
