自定义dragulaR [Shiny]以使用下拉列表进行预填充

Question

我正在使用dragulaR创建一个应用，我希望用户能够从下拉菜单中进行选择，并且可拖动元素将从拖动区域fun! Split() let line = getline('.') let result = [] for l in split(substitute(line, '[{}]', '', 'g'), ",") let result += ExpandIt(l) endfor let lnr = line('.') call append(lnr, result) exec lnr'.d' endf fun! ExpandIt(line) let pat = '^\(.*\)\[\(\d\+\):\(\d\+\)\]\s*$' if a:line !~ pat return endif let exestr = substitute(a:line,pat,'range(\2,\3,-1)','g') let text = substitute(a:line,pat,'\1','g') exec 'let range='.exestr let result = [] for i in range call add(result, text.'['.i.']') endfor return result endf nnoremap <F6> :call Split()<cr> 移至拖放区域{{1} }：

如图所示的所需结果：用户从下拉列表中选择B，并将B块放置在alphaBlocks

内
