The platform allows to create loops and display results over:

• Filter data [Step by step example →]

In both these examples we will take the following steps:

You can take a look at how it's implemented in Demo App in your account, screen - 13 Operation Loop Screen.

Note: we only use at sign (@) to reference Object properties (#Loop:AgeEmailLoop:objects@Age#). When referencing Operation, we use colons only (#Loop:Holidays:date:iso#).

DATA FROM LISTS OF TABLES

You can loop any data from any of your custom Lists of Tables. Pulling data arrays from lists of tables is available anywhere, where there is a Loop, including on slider components, etc etc. 

For example, using existing tables in you Task Manager sample app, we can do this to show all languages available for it's users, which are stored in table named "languagelist" and in column named "language"

Steps taken in this example:

1. A button added to a screen

2. Enable Loop on the button, marked purple ↓

3. Insert a hashtag with the List you want to use as Data Source, marked green ↓, as example, #List:languages:languagelist#, where:

   1. List = a command to address lists of tables in hashtag

   2. languages = a name of a list we have in this sample app

   3. languagelist  = a name of the actual table you are referring to

4. Name the Loop, as how it can be referred later on, marked red ↓, for example - ShowAllLanguages

5. Refer to this named Loop in any place of a button, in this case in Caption section - #Loop:ShowAllLanguages:language# , where:

   1. Loop = a command to show that some data needs to be pulled from the Loop

   2. ShowAllLangues = a name of the loop we have given before

   3. language  = an exact column name, which you are pulling from the list and need to iterate.
