How to edit a dataset on a page?

Anyone know how to set up a web page so that people can edit a dataset on a live web page rather than have to log into the dashboard?

I have set up a form to enable my client to add information to a dataset but cannot figure out how to set up a way to edit the information on the same page, possibly through a form or something…?

Is this possible?

It is for a sports team who will need to be able to edit their fixtures and add new ones when needed.

Just be easier to allow them a designated role for your website, so that they have access to certain parts like Wix Events to add any events on your site etc.

Another option for you is to take this tutorial and modify it to suit your needs with the page being setup for a member of your sports team to edit for example, like in a certain member role within their site member. They can be an existing site member for the sports team that you simply designate say a Sports role and they can have access to that page only, see below tutorial link for links on how to set that up.

You can simply change the tutorial setup to suit your own sports team, so the first dynamic page shows their existing details like events etc. Then the update dynamic page can be where they go and change any existing events or add new events etc.
