Here are the widgets we have discussed on this site. You can see the demo, read the tutorial and download the complete code. Though most of the widgets can be inserted on any platforms, some cases we have specially made it for Weebly.
These widgets can be added on your site without any modification or with minor modifications to suit the layout of your site. Filter the widgets based on the category, date and name or use the search icon on the top right position on the menu bar to find the widgets for your website.
