Hey everyone!
I am currently working on a mashup in which I have to list-widgets as shown below.
The first list-widget has two elements, for example: Ferrari and Porsche
Depending on which element is selected, the second list-widget should be filled with a pre-defined list of either Ferrari-car-tag or porsche-car-tags.
It is like a filter mechanism.
Is this even realizable and how?
Thank you as always for your help
Best regards,
Theresa

Hello Theresa,
Here is how I solve the problem:
1. create a datashape with 2 fields: String and Infotable. The first String is for main brands like Ferrari, the infotable (holding Strings) is for sub-brands.
2. Create a Datatable based on the datashape and add values inside
3. Create a Mashup, import the Datatable - GetDataTableEntries service, bind All Data to first List, bind Selected Rows to second List
4. Choose related fields in different List widget
5. View mashup, it would work

hey Ryan Yuan,
first of all, thank you so much for your detailed answer!
I have one question left:
As you suggested, I have added a Data Table-Thing and am now trying to fill the data table with my static values:
I can add the Brands (ferrari and porsche) without problems, but how can I add the subbrands?
best regards,
Theresa
As you can see in the first picture, when I created the Datatable, firstly I created a datashape used in here.
The CarBrand is a String shaped property, it can hold Ferrari
The SubBrands is a Infotable shaped property, and it looks like the New Field part I just added. This Infotable is a little table that can holds a list of data, and you need to assign another Data Shape for this Infotable. In the Demo I showed you, the SubBrands field contains a Key field to hold numbers, and I put detailed versions inside.
This image I posted comes from AddDataTableEntries service (default) in the entity
The little Orange Button with Edit in the picture means this field is a Infotable shaped property, and you need to click to open and add data inside.
hey Ryan Yuan,
concerning this topic: Is it also possible to somehow change the values inside of the subitems-infotable?
Because I have also added the location of the specific ferrari-cars and porsche-cars(subitems) by now. But as the location of the cars can change, I want to change the value in the infotable as well (because I have added them manually and not dynamically in a service).
This is how far I got in implementing my own service:
After the last line of code, I have to update the subitem-infotable with a new value but I do not know how to accomplish that.
I have seen a function called UpdateDataTableEntry(params), but I think this will not work out for me because I haven't instantiated a DataTable-Thing for the subitem-infotable. I hope you somehow understand what I mean.
Thank your so much in advance
Warmest regards,
Theresa
Hi Theresa,
You can run this service
The CarBrand is the first layer Key word to focus the Subbrands infotable, and for Subbrands you can send in an infotable typed data.
Hi, it's actually in AddDataTableEntries service in Datatable entities. Clicking the Edit Button I marked you will find the Editing Infotable
