I Just started with your components and Ran into an issue with the AutoComplete. I have a Load from SQL Server. The Array gets Loaded but the AutoComplete suggestions only Show Up of I leave the with with Tab or click into another Field. Do you have any Idea what could cause this behaviour?
I Just did some Test. I copied the Demo source in my Project, and it seems its only an issue with the AutoComplete with custom filtering (wich I used before too). The other three are working flawless. And this one hast the same behaviour in your site
I finally figured it out. The Autocomplete fields dont display content if you go with TAB through the fields. If you first click in the emtpy field it works (for the first three in your online demo). The AutoComplete with custom filtering shows always this behaviour. So this should be reproducable in your demo. I tried with Microsoft Edge and Chorme Browser.
