Hi, Is there a node that allows the user to select from assemblies present in a file, similar to how you might select corridors, surfaces and alignments? ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/b/e/beaa076598701f13eebde3338d41d6439947f453.png) ---

@hosneyalaa thank you for the reply but I need to be able to select the finished assembly from a list of assemblies not subassemblies. I can type the name in as an input (see image) but a drop down like what is available for other elements would work better. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/2/5/25e38bfe41367ab0489c5b0631eb47f1e13dc920.jpeg) ---

There is no dropdown node for assemblies ---

HI @bourke_d From the attached example of @Anton_Huizinga > [@C# Dropdown](https://forum.dynamobim.com/t/c-dropdown/17503/12): > > “Next week” was a bit optimistic but finally I was able to do some testing. And I got result. There are two things you should know: It seems not possible to combine UI and Zero Touch nodes in one DLL so you need to use a seperate Solution to build dropdown nodes. It only works if the DLL is loaded via a package, not with the ‘import library’ function. You can download a sample Visual Studio Solution below (without de compiled DLL file). Two classes are available. One to create a dropdo… try this After put the attached file in this path ![312727778_6016249138490748_1289462728248194522_n](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/0/e/0e688bb004ce2f6ee3b7d89d52f03b3ed0954b58.jpeg) ![QQQQQ](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/2/7/27a281324c203fd6396f21737419ffee503ccf96.jpeg) [https://www.mediafire.com/file/rvdtg2jkwph3isr/Assembly.rar/file](https://www.mediafire.com/file/rvdtg2jkwph3isr/Assembly.rar/file) ---

@hosneyalaa thank you I tried that, and it worked on the first pass but if I run the script again a second output appears and causes an issue: ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/9/6/96b84c3af284b7df084a98f294c89ab0b3d12cca.png) ---

@hosneyalaa - I run the script fine it works - I close the script - open it again - there are now 2 outputs. hopefully this video will explain the issue better: [https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/d/0/d075db764393cba4949755281ae157be261d6ab8.mp4](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/d/0/d075db764393cba4949755281ae157be261d6ab8.mp4) Perhaps I am missing somethig. ---

You need to add a JSON constructor. > [@UI Node Extra Output Ports](https://forum.dynamobim.com/t/ui-node-extra-output-ports/67215): > > I’ve created some dropdown nodes that inherit from DSDropDownBase and the issue I’m having is that an extra output port is created every time the graph is saved and reopened. Also after saving and reopening, an exception is thrown saying that “an element with the same key but different value already exists.” Any ideas? While this is admittedly a pretty cool trick I’ve stumbled upon (who doesn’t want a node that evolves over time?), it’s not what I was going for … ---
