Help with output - iframe too small

Using Streamlit
1

I have a small issue: my code works, but Streamlit is showing it in a miniscule iframe so it isn’t actually usable. The code is below and a picture of the output is also.

Could anyone perhaps help?

Hi @ryanblumenow ,

The components.html function accepts width and height arguments, so you can adjust the size to your needs. API reference here: Components API - Streamlit Docs

Hope that helps :slight_smile:

That’s awesome, and yes it is working now. I had to integrate the height into the components.html function as well as include the CSS code for height of the frame/HTML stage into the content of the JS code.

Is there a way to determine via the code what a user clicked on and from there to do something in Streamlit? e.g. if the user clicks a particular picture in my JS/CSS code, then I can set a variable and from there tell Streamlit to do something based on the value of the variable?

My skillset is limited so I don’t know if what you ask is possible :slight_smile: Maybe someone else can answer (though maybe the way to go is to create your own custom component, which allows for inputs and outputs).

I wrote a detailed tutorial on Streamlit components, which includes one that’s a pure static HTML/JS implementation. Give it a whirl… have some fun. :balloon:
