About ImmediateGUI
An IMGUI inspired GUI Framework for javascript thats designed to be as simple to use as IMGUI.
Its actively developed, which means stuff might change and bugs (most definitely) will occur when using this
Supports most of the default controls one could need, can drag the gui around with the mouse, toggle between light/dark mode etc.
For how to use it, check the example code down below (and look at the code of the library)
Example Images (and pseudo code how they were made)


const $$ = new ImmediateGUI({
theme: 'dark',
position: 'left',
width: 400,
draggable: true,
});
$$.Header("Example Header", 5);
$$.Button("Example Button");
$$.Textbox("Example Textbox");
$$.TextArea("Example TextArea");
$$.Label("Example Label");
$$.ProgressBar(64, 0, 100, true);
$$.ColorPicker();

$$.Dropdown(["Option 1", "Option 2", "Option 3"], "Option 1");
$$.NumberInput("Example Number Input", 0, 0, 100);
$$.Slider(1, 100, 25);
$$.Checkbox("Example Checkbox", true);
$$.BeginSection("Example Section (Non collapsable)", false);
$$.Button("Control inside section");
$$.Textbox("Textbox inside section", "GAGA");
$$.EndSection();
$$.BeginSection("Example Section (Collapsable)", true);
