javascript - Positioning a Dropdown Where Button Was Clicked -

-

i have alloy ui dropdown component want render when user clicks on 1 of 4 buttons - dropdown should positioned left of button clicked

var toolsdropdown = new y.dropdown({     boundingbox: '#my-div',     trigger: '.option',     hideonclickoutside: true,     hideonesc: true  }).render();

i dropdown menu render wherever position of button clicked (imagine these buttons displayed in each row of table)

<div id="my-div">     <div id="container-1">         <button id="options-btn-1" class="option"  type="button">option one</button>     </div>     <div id="container-2">         <button id="options-btn-2" class="option"  type="button">option two</button>     </div>     <div id="container-3">         <button id="options-btn-3" class="option"  type="button">option three</button>     </div>     <div id="container-4">         <button id="options-btn-4" class="option" type="button">option four</button>     </div> </div>

i have listener setup listen each button clicked

y.all('button.option-btn').on('click', displaydropdown);

however i'm having trouble getting function (maybe don't understand how alloy's dropdown works) - ideas?

edit: think might fair better yui's overlay widget

overlay positionable , stackable widget, provides support standard module format layout, header, body , footer section.

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
