I want to know on how I can put an image beside the text
Thank you in advance

BLOCKS PART
in designer view, select Listview, change property ListViewLayout to Image Main text, DetailText.
But your block to setup elements have problems.
what should I do next? I'm asking because I'm not good at this and it's my first month of creating apps
Hello Abdul. We can't do your homework for you. You have done well, just follow Kevin's hint. You could try making a mini test project that just uses three or four items of text along with matching images. Ensure that the images you use are free to use.
Can I at least get a hint on what's the problem with the element block?
You have the entire list 'lista' going into one main text of the List View? That should be a List Item (Select List Item). What happens when you run your App in the Companion? Does the result not tell you something is wrong?
When you tap on 'muffin' does it highlight on it's own?
it highlights when touched, but then It goes back on the screen 1 because I didn't do the screen 2 with all the other things
The names (e.g. muffin) should be the 'Main Text', the price (e.g. €2.29) should be the 'Detail Text'
see the docs:

oh, now I understand, thank you

MY IDEA
Where do you plan on getting those images from?
I don't know yet, any type of source will be okay because I have the url of all images (I can upload them locally too)
Depending on how static your images and names will be, either:
Best to download them, make them all the same size and convert to WebP format - needing a connection to the cloud is a risk - the website(s) might change their pages and make the URL null and void - or have a different picture for a different subject.
It's very important to ensure there are no copyright issues. You could take your own photos.......
oh ok, I can create them from Photoshop and download them in webp
hello, it's me again, I want to know if I upload every image in drive and open them as image it will be better cause the url won't change, and I want to know if 1080x1080 would be okay for the webp images
Hello Abdul
1080 x 1080 is far too large. The images should be scaled down to just over the size they will be on the phone. In a Listview, experiment with something like 100 to 200 pixels. See my general guidelines on images:
