LeadSquared now supports drop-down fields whose values can be linked to value selected in another drop-down field. The most common example is showing States based on selected Country.
LeadSquared achieves this by letting you establish parent-child relationship between any two drop-down fields and then letting you specify value sets in child corresponding to each value of parent. Multi-level dependency (for example: Country -> State -> City ) is also allowed. Note: the dependency will show on Lead add forms of LeadSquared. We will extend the feature to landing page forms very soon.
Check the feature at: My Account -> Settings -> Customization -> Dependent Lead Fields.
