Fileuploader - Changes with slots

[sabirveli]

the file upload component…. keep reimplementing it for different looks
needs unifying.. it should be something like..

<div class="kws-file-upload">
<slot {prop1} {prop2} >
<!--ui goes here-->
</slot>
<input type="file /> <!--absolutely position-->
</div>

• Design from slot
• Multi file upload support
• Drag and Drop feature
• Cloud upload

Note : so almost everything goes via slot props.. so we can build different looks while not having to copy same js code to another file to make a variation..
we also copy/pasted same file in othe rprojects to make it wirk slightly different
for apparel we did one version for main apparel.. and a cloud upload version for prodsys
see if you can unify everything
including any backend changes we added for cloud upload
