Hi @ananth
If you need to make values from UI available to your backend, you will need to make use of some JS in order to pass those values into a backend endpoint. The endpoint will use those, perhaps with other computations in order to generate a response.
JS then will, if successful (or unsuccessful) update UI.
For example in HTML
<div> <input type="text" id="input_field" value="some_value"> </div>
Then in JS perhaps you want to capture when someone clicks on this (or other events)
$('#input_field').on('click', function () { input_value = $(this).val(); $.getJSON(getWebAppBackendUrl('/do_something?input_value=' + input_value), function(data) { do_something_in_UI(); }); });
then in Python backend
from flask import request import json @app.route('/do_something', methods = ['GET']) def do_something(): input_value = request.args.get('input_value') return json.dumps(some_dict_response)
Please treat the above as pseudocode to illustrate the general flow, hope this helps!

Hi @moumita_biswas
,you have to have it updated in /libedition/localstatic "Static Web Resources"
and have that referred in your HTML as <link rel="stylesheet" href="/local/static/CSS//bootstrap.css" />
