Responsive UI with Streamlit/Python

I explain how to get current UI width info in Streamlit and use this value to calculate number of columns to be generated for the form block. Streamlit is server side UI framework and it runs on Python.

 

Calling JavaScript from Streamlit/Python

Streamlit is Python framework, it helps to build UI with low code approach. Code runs on server and there is no functionality, which would allow to inject client side events with JavaScript. Luckily there is a 3rd-party Streamlit component, it allows to make JavaScript calls from server side Python code. Response from such JavaScript call is received within the same Streamlit execution, this makes it possible to use values returned from JavaScript in Python logic. In this example, I show one liner JavaScript call to get UI screen width, to be able to calculate layout structure adjustments in Python, based on the screen size.

 

Building Streamlit/Python Dynamic Forms

Streamlit is great to build Web UIs for data apps. Dynamic UIs are common requirement for data apps. Data structures usually dynamic, set of attributes is changing and this requires dynamic UI. I explain how to generate dynamic forms with Streamlit. It works very smooth.
