Hoping someone can help - I've spent ages searching for the answer online but can't quite find what I need!
I'm trying to create a selectizeInput that is filtered by another selectizeInput.
I have a list of schools that are in different areas, I'd like my first selectizeInput to mean that my second only brings up a list of schools in the selected area. I've copied the inputs below.
selectizeInput("LASelect", label = "Filter by Area:", selected = "", choices = c(ASData %>% filter(!is.na(LA)) %>% select(LA) %>% unique() %>% arrange(LA)), multiple = FALSE), selectizeInput("SchoolSelect", label = "Filter by School:", selected = "A Primary School", choices = c(ASData %>% filter(!is.na(School)) %>% select(School) %>% unique() %>% arrange(School)), multiple = TRUE)),
