Build a Mutli-Select Menu with an External Data Source using Block Kit and Slack API

Front End Code (Including Manifest File): https://glitch.com/edit/#!/multi-sele... Back End Code: https://glitch.com/edit/#!/wooden-fan... This video walks developers on how to build a multi-select menu that has an external data source using Slack APIs and events. So in this demo, I want to show you exactly how to how to use a multi-select menu and basically use this to add tags. So this could honestly, you know, this could be anything but the main idea is to autocomplete whatever I'm typing in and to have a back end that will be able to search and return results that is matching what I'm typing in. So here is my frontend code, and you can see it's called Multi-Select F-E, and this is all. I'm going to share this code with you all so that you can and play with it. But it's basically only about 92 lines. And what we're doing is we're subscribing to the App Home Open event and basically, once we open, we're going to publish this view and the View is going to have the multi external select and then one button, which will will have the text submitted in it. Once they hit that button, it'll have this app action, which will say submit button clicked and logged all the values. So again, if I type submit right here, actually, I need to configure the app really quick. So and I'll make this very nice and easy. Basically, we can go to Slack API and click Create a new app, and we'll use from App Manifest here and we'll just pick your workspace. And basically, I have this Manifest YAML here, and I'm just going to copy and paste it, and I'll paste it in here and you can see. So I'm going to make a couple of changes. I'm just going to make this YouTube two so that you can differentiate from my other apps. What I've done is I've added the bot chat:write scope. I subscribe to the App Home Open event, that's that. So we can open the app and you can see that multi select frontend glitch is the request URL that we're using here. And then again, we're doing interactivity. You can see here and the request URL is the same the multi select frontend glitch. The only thing here is we have this message menu options URL. That's the backend for populating the actual options of the menu. Now, the only thing we have to do is really three things 1. install your app to the workspace and then 2. grab your environmental variables and add those into glitch. So let's go ahead and install the app. We'll click Allow. Now my my app has a bot token, so let's go into OAuth & permissions and we'll copy this bot token and I'll go into my end and I'll I'll add in this bot token. Now we'll go back to basic information and we'll grab this signing secret. So that was actually my mistake. I accidentally took the client secret instead of the signing secret. So let's go ahead and use that. That's why we're seeing some of those errors. OK, now let's try this again if I refresh. You can see that the app home is working, and if I type in P-Y-T, it should auto complete with Python. Perfect. And if I hit submit, we'll be able to see that result on our logs. So again, basically I showed you, but someone clicked and we see the value of Python there. So yeah, I everything is working as intended. So now let me show you the back end code. So here is the backend code. And what we do is in App.route/slack/events And then again, this is the URL, right? If I do, if I do share, here's the life site. All right. So that's what I used for my slack events. Basically, what I do is I get the substring, which is usually those three characters that I type in. And here is my hardcoded external data source. So you can imagine, you know, looking up in your database or doing an API, call to your external service and populating an array right where you have all these possible options, where your user would start typing in and your menu would autocomplete that right. And for me, it's only these four things, and I just want to make it as simple as possible. So that's why I do this. but anyways, for i in range We're going to look for the substring. So if are what we typed in those first three characters is in the name array, which is basically our data source. Then we're going to match it and have that be the option. Otherwise, we're just going to let whatever the user typed in. We're going to let them add that. And here's where we make our response of ATP 200 and where we set the content type two application JSON. So that's more or less it. You can go ahead and use this code. I'll have all the code linked in the description, but basically, now you understand how to use this multi select menu and have this pretty dynamic and powerful filtering mechanism for that. When your user starts typing and you can kind of autocomplete and and have a great, delightful user experience.
