Building cascading filters in Retool
Blog post from Retool
A technical account manager at Retool provides insights into implementing cascading filters within the Retool platform to enhance data exploration tools, particularly for engineering teams. This process involves using Retool's intuitive interface and JavaScript capabilities to create a dynamic filtering experience by narrowing down data through hierarchical selection criteria. For instance, selecting a country updates state and city options accordingly, facilitating efficient navigation of large datasets. The guide outlines how to set up cascading filters using components such as Select dropdowns and Tables, with a focus on JavaScript logic to update filter options based on user selections. This approach is applicable to various hierarchical datasets, enabling teams like HR or support to refine data views efficiently. The document also highlights how the completed application can be downloaded and imported into a Retool instance, encouraging users to explore and implement cascading filters in their projects.
