stateSave - previous state settings not shown in filter boxes

[vnijs]

Followup on #76

In contrast to the Search field the filter boxes do not 'remember' their values after refresh. The input list does have the previous values but the boxes don't show them.

Question: Would the state information be shown in the DataTables column filters (i.e., like the 'old' column filters in shiny::datatables)? If so, would it be possible have an option to use the 'old' filter boxes? Obviously the 'new' filter boxes have greatly enhanced functionality but for my app saving and (re)loading state is a key feature.

As a follow-up (same issue) can you set the initial search value for column filters? You mentioned in #76 that the initial search and order could be set but didn't mention column filters. If this is possible, and if they would be shown in the column filter boxes, I think (hope) I could use this to save and reset state. I did notice however that saveState overrules the value set for DT using the search = ... option so this approach may not work.

I have made the column searches available via input$foo_search_columns (without having to use stateSave = TRUE). You can set set initial searches for individual columns via searchCols: http://datatables.net/reference/option/searchCols e.g.

datatable(iris, filter = 'top', options = list(searchCols = list(
  NULL, list(search='5.4 ... 6.8'), NULL, NULL, NULL, list(search = '["setosa"]')
)))

Note searchCols should be a list of lists or NULLs.

Great! Does global search and sorting need saveState though?

For global search, no: http://rstudio.github.io/DT/shiny.html For sorting, yes.
