This tutorial walks you through building a screen flow that allows users to select multiple car manufacturers (e.g., Tesla, Ford, Honda) from a multi-select combobox. The selected manufacturers dynamically filter the data displayed in a configured data table below, showing only the car models from the chosen makers. Learn how to use reactive formulas to achieve this real-time filtering and create a more engaging and efficient user interface.
This formula filters the data table based on the multi-select combobox. Here's how it works:
Car_Make__c: This is the API name of the field on your Car object that stores the car's make (e.g., "Tesla," "Ford"). Replace this with your actual field name.
IN: This operator checks if the car's make is one of the values in the list.
{!combobox.valueCollection}: This refers to the collection of selected values from your multi-select combobox. It should work as is, assuming your combobox component is named combobox. The & are used to concatenate the values.
("& ... ")": The parentheses and quotes ensure that the values from the collection are correctly formatted for the IN operator.
Copy and paste the formula, and remember to replace Car_Make__c with your field's API name.
Feel free to adapt this formula to your needs. For example, you can add more conditions using logical operators (AND, OR) to filter by other criteria. You can expand this formula to incorporate selections from other Avonni combobox components or others within the Avonni Components Package. This allows you to create highly dynamic and interactive filtering experiences.
