Add the ability to hide symbol type in results or present symbol type as virtual text that is not searchable

[srgsanky]

Is your feature request related to a problem? Please describe.

When I lookup the document symbols in a markdown file (using marksman lsp), telescope shows all the headings along with the symbol type which is always String. If I have a markdown file say on the topic of Rust and I have a section titled String, I cannot get to it by looking up the document symbols as String matches with the type of all the headings.

I tried setting symbol_type_width=0, but that defaults to 8 when set to 0.

telescope.nvim/lua/telescope/make_entry.lua

Line 519 in 37dc923

table.insert(display_items, #display_items, { width = opts.symbol_type_width or 8 })

Describe the solution you'd like

Option 1: I need a configuration to hide the symbol type based on filetype.
Option 2: Present the symbol type using virtual text which is not searchable using Telescope.

Describe alternatives you've considered

Currently, I duplicated a set of functions from telescope to overcome this. I use a custom document_symbols (that is mostly a copy from Telescope) and uses a custom entry_maker for markdown files and won't display the symbol type. https://github.com/srgsanky/kickstart.nvim/blob/master/lua/custom/plugins/telescope_custom_document_symbols.lua
