Dropdown anguar material component

Hello, I need a pretty specific angular component. I am a developer myself but need help! If this work is completed quick, clean and fast we'll work together in many other projects. Here are the requirements: * Needs to be done using angular material auto-complete and the CDK virtual scrolling component. * When the user clicks in the drop down, a table must be shown (the table is read only, so a flexbox table is good enough). * It's super-important to offer keyboard support. The table must be expanded when the component has its focus and the user must select and element by using the arrows keys. They need to use Enter to select an element. The table must collapse when the control lost its focus. * The table needs to be filtered when the user starts typing. It needs to search by all the rows. * The performance it's really important. We need to show the drop down content as soon as possible by using the virtual scrolling from the Angular Mateiral CDK. * You will have two inputs: a) an array of columns. Each column will have type (text, currency or date), title and id. Example: [ { id: 'name', type: 'text', title: 'Address', width: 100 }, { id: 'address', type: 'text', title: 'Address', width: 300 }, { id: 'balance', type: 'currency', title: 'Balance,' width: 100 }, { id: 'duedate', type: 'date', title: 'Balance,' width: 100 } ] id will point to the right field of the 2nd input. title is to show a column title when the dropdown is opened. type is going just to format the data correctly. width is for the column in the drop down table. b) The content is the 2nd input of this component. We'll use an observable with an array of <any>. The content will have something like [ { name: 'name 1', address: 'address', balance: 100.31 duedate: '2019-01-01' }, (between 1 and 10000 rows) ] Output: * The selected row or null if no selection is made. Misc notes: * We need the out-of-the-box angular material style for the closed dropdown. * The internal table needs to be close to angular material. Deliverable: An angular 7 (or 8 compatible with 7) project with a demo page.
