Experience

Salesforce Recurring Events for Lightning

Until late 2018, there was no way of creating recurring events in Lightning, which caused many users to delay adoption of the new UI. In response to this, I have created a custom Lightning component that provided the same options as the original Salesforce classic recurring events section as in a standard new event page. The component was presented after a user clicked a button on an event detail screen—this was required to keep the event creation page standard. Selecting the desired recurrence parameters and saving it caused the event to transform into a series of events.
