Hello.
I have problem.
I have css style on: body {direction:rtl;}, after this appears scroll to the left on the page on mobile device.

P.S. Yo can see it on http://www.dropzonejs.com in browser by adding above style in debugger tool.

How to limit maximum number of upload?

There are no class structures of ".table" on div elements with Bootstrap 4 and converting to a table structure breaks dropzone.js

Remove the class="table table-striped" of #previews and replace file-row class with <div id="template" class="d-flex justify-content-between">

Hello,
I use the template you created. but add items don't work

hello everybody. this is the worst documentation I have ever seen so far. Unfortunately author missed to explain that those codes are for only container previews. It means they will not work unless you place relative form or div that triggers all those. Copy paste won't work. Obviously something has been changed while versions go up and old documentations still stay there and huge disconnected structures there in. If you were the first consumers you would understood them all but now with those information this is very hard to to grab it from zero knowledge. I advise you all to change your mind and give up to use this module.

I know that this has been posted 5 years ago, but, if you get this error Uncaught Error: Invalid clickable option provided. Please provide a CSS selector, a plain HTML element or a list of those. you need to make sure that the css selector for you button actually exists.

@ShinodasCodes sorry you're frustrated. It's true that I let the documentation slip a bit, but it's tough maintaining a project for such a long time. I'm doing my best to get it up to a good standard right now.
