Ah, ok. Sorry for the confusion 
Open the settings screen in the designer mode of Thunkable then find the list picker object and edit the value that has the sources to contain the sources you want
You can find the sources here
It was very good !!!
Would you be able to adapt it to use with Blogger? I have long wanted to create one with this appearance instead of a simple web view. Would you give a force?
The blogger’s api code is a bit different

If what you mean by “give a force” is to attempt to make the app then yes. I would be more-than-happy to make an app like that. Although I have never used Blogger I am sure you will find a use for the app 
link api blogger https://developers.google.com/blogger/docs/3.0/using#WorkingWithPosts
I tried to put the blogger’s apis, but I can not, they are different.
I’m new to Thunkable, I’m trying to understand its structure, but I still do not get it … rsrs
If you could do what you did with blogger posts would be very good. Currently I have an app with a blogger webview, but it is not as pretty as yours.
I think it would not be too difficult to fit the blogger’s apis framework into your app. If it worked out the rest of the design and etc I would do it myself.
Sorry for the errors, I’m Brazilian, and I’m using google translator 
If you would like JSON works in Thunkable even more than you do you should check out this post I made a while ago An easy way to decode JSON I will make the Blogger thing I just have to go for a bit. It is a simple post easy to read.
I’m still breaking my head here,
I’m new to thunkable, but I’m trying here, but if you can, please post here to help, I’ll be grateful. A hug partner.
