I've got the uibuilder simple example running. Now I'd like to be able to control the button on the front-end side depending on uibuilder (either onchange or node-red msg) hopefully my request is clear. ---

> [@dedicatedtek](#): > > hopefully my request is clear. Indeed, not so much... Anyway, using uibuilder implies knowing how to code a web-app. You can find a lot of documentation on the latest version [here](https://totallyinformation.github.io/node-red-contrib-uibuilder/#/uibuilder.module). Then, if you have more specific question, please add your code snippets. ---

I started with this example: > **[Example, MoonJS with Mini.CSS · TotallyInformation/node-red-contrib-uibuilder...](https://github.com/TotallyInformation/node-red-contrib-uibuilder/wiki/Example,-MoonJS-with-Mini.CSS)** > > Easily create data-driven web UI's for Node-RED using any (or no) front-end library. - Example, MoonJS with Mini.CSS · TotallyInformation/node-red-contrib-uibuilder Wiki it works, easy to get it going. I want to be able to alter / modify / update the web ui - for instance, I want to be able to disable or hide the button. I saw this ("msg.\_ui.method - update") here: > **[uibuilder Technical Documentation v5](https://totallyinformation.github.io/node-red-contrib-uibuilder/#/uibuilder.module?id=available-methods)** > > uibuilder Technical Documentation v5 but I just couldn't seem to follow the info. would love to have a working example - if this will accomplish the above. thanks. ---

Perhaps this example may be of use to you. It demonstrates the use of a `uibuilder` sending and receiving messages. ```auto [{"id":"da65bd5fe4671fb9","type":"inject","z":"86a82b7c66374659","name":"8

As it says in the wiki article, that example was written for uib v1 and updated for v2. We are now on v5 and a lot has changed since then. Unfortunately I don't have time to update all of the old examples myself and I don't use frameworks like moon myself anyway. So unless other people step up and update the articles, unfortunately you need to compare against the current templates and check for any breaking changes in newer versions of moon as well. > [@dedicatedtek](#): > > but I just couldn't seem to follow the info.
