Preview height when vertical layout

[idr4n]

Hi,

I was wondering if it is possible to achieve something similar to the preview in Telescope's get_dropdown theme. That is, the preview is on top of the picker window and occupies whatever space is available (whiteout shrinking the picker window). In Fzflua I get a similar look, but when I trigger the preview, the picker window adjusts accordingly.

Here is a video for clarification:

My current settings are these one:

  opts = function()
    return {
      winopts = {
        preview = {
          vertical = "up:50%",
          layout = "vertical",
          scrollbar = false,
        },
      },
      winopts_fn = function()
        local max_width = 120 / vim.o.columns
        local max_height = 20 / vim.o.lines
        return {
          backdrop = 100,
          width = math.min(max_width, 0.8),
          height = math.min(max_height, 0.8),
        }
      end,
      fzf_opts = {
        -- ["--layout"] = "default",
        ["--layout"] = "reverse",
        ["--info"] = "inline-right",
        -- ["--layout"] = "reverse-list",
      },
}

Thanks in advance!

This is possible with previewers.builtin.toggle_behavior = 'extend', see #721 for more info and how to configure:

require("fzf-lua").setup({
  previewers = { builtin = { toggle_behavior = "extend" } },
})

Thanks a lot for the quick response. That's what I was looking for. Sorry I missed 721.
