appearance panel search shown as not floating pane

[jeusdi]

I've just installed mrjones2014/legendary.nvim.

It seems to work well, however I'm not getting an appearance behavior similar to floating window panel to search. Here you can see, what I mean into this asciinema.

I was expecting to get a floating panel like shown into landing github project page.

My current configuration is here.

Any ideas?

See https://github.com/mrjones2014/legendary.nvim#prerequisites

Also, for the which-key auto-register functionality to work, looking at your config, you'd need to rearrange the lines like this:

require('legendary').setup({ which_key = { auto_register = true } })
wk.register(mappings, opts)

Rather than calling wk.register first.

Thanks @mrjones2014 .

I already read above suggested prerequisites section but I have not quite understood it at all.
Does it means that I need to have installed both telescope and dressing? Or only one of them? Currently I've installed telescope (nvim-telescope/telescope.nvim). I also need dressing plugin?

[mrjones2014]

telescope.nvim provides the fuzzy finder. dressing.nvim hooks it up to vim.ui.select() which is what legendary.nvim uses internally.

So to mimic my setup you will need both of those plugins, however there are also some alternatives like fzf. But, you will still need something that hooks them up to vim.ui.select(). For that I'd recommend still using dressing.nvim. It supports wiring up vim.ui.select() with telescope.nvim, fzf.vim, nui.nvim and a default built-in select backend.
