Example 2- drop-down list
While visualizations and control extensions are very similar and both rely on the same underlying libraries, building a control component as an example will highlight a different set of methods and objects that can be utilized to construct user-friendly components to interact with the app's data.
Requirements
To keep things simple, the requirements will be relatively straightforward to also illustrate that building simple extensions, such as a drop-down list, can be achieved in a short period of time. For the example, the requirements will be as follows:
- Display dimension values in a drop-down list, allowing the user to select one value at a time
- Give the user the ability to specify the chosen field themselves via the property panel
- Implement the ability to also show the frequency of dimension values in the data model
- Implement the setting to turn your drop-down list into read-only
Folder structure
The folder structure will be identical to the best practices already described...
