Hi :)

You don't have to use fmt here, you can generate the insertNodes and textNodes manually:

s({trig = "div(%d+)", regTrig=true}, {
	d(1, function(args, parent)
		local nodes = {}
		for idx = 1, parent.snippet.captures[1] do
			table.insert(nodes, t"<div>")
			table.insert(nodes, i(idx, tostring(idx)))
			table.insert(nodes, t"</div>")
			-- add a linebreak
			table.insert(nodes, t{"", ""})
		end
		-- remove trailing linebreak
		nodes[#nodes] = nil

		return sn(nil, nodes)
	end)
})

fmt does not work well here because it returns a list of nodes, so nodes looks like

{ {node1, node2}, {node3, node4} }

instead of the expected

{node1, node2, node3, node4}

Thanks for responding..and i appreciate your solution. Via Similar approach i made it work somehow by using vim.list_extend(nodes_array,fmt node)...thanksto rededit community support I was able to achieve this....I would like to mention user who helped me there ..https://www.reddit.com/u/justinmk/s/Atjm7HPRUw

i have question that what if our luasnip snippet is child of lsp snippet .. i m making php snippets for html file ...seems indentation goes way off the line.. outside tags snippet working fine though when i enter any html tags it indents my newline to way much

Oh, there could be many reasons for this, could you share the php and html snippets you used there?
