When a button is pressed, I want to close the menu bar. Help.

(Looking in order,)

  1. Press the Home menu
  2. I want the menu bar to disappear automatically.

Do you know how? Help.

Given everything is defined inside your HTML & CSS files, in order for your JS file to access it use p5js select() function:
p5js.org/reference/#/p5/select

Your whole menu is wrapped up inside a <div> element identified as class “wrapper”:
<div class="wrapper">

So you can reference that as a p5.Element in p5js like this:
wrapper = select('.wrapper');

Then you can hide the whole thing via method p5.Element::hide():
p5js.org/reference/#/p5.Element/hide

However you only wanna hide() it when any of the buttons is clicked.

So you’re gonna need to define a listener for it:
p5js.org/reference/#/p5.Element/mousePressed

Your both buttons belong to a <ul> tag w/ id “list-items”.

I’m not sure but I guess it’s worth trying to set the listener to that <ul> element:
select('list-items').mousePressed(() => wrapper.hide());

Thanks for your reply.

  1. Controlled ‘hide’ as you said.

  2. However, what I really needed was

<input type="checkbox" name="check_boxx" id="btn" hidden>

I want to make ‘id=btn’ ‘checkbox’ false. Is there any way?

If you need to access properties of the element itself you’ve gotta do it via p5.Element::elt:
cbox.elt.checked = false;
p5js.org/reference/#/p5.Element/elt

Thank you very much.
You are a genius.

And one please.
Do you have any study materials or videos related to p5.js?
Thank you for recommending it.

Thank you very much.

[Solution]

  cbox = select('#btn');  // cbox = select('#btn');
  cbox.elt.checked = false;
