Question about sharing folders with Mac and Ios

Hello everyone,firest at all, I would like to thank Anonmous and Tayler for the 2 podcast that they did about that topic. In those podcast, I understood that we can share a folder sinding to the other person a link, but, I wonder me if it's possible as well, creating a shared folder, in the same way taht we do it, for example, in Dropbox, I mean, a folder in which all the people who share it, can enter, put and take files, or folders from it.
.
Many thanks in advance.
