Wordpress widget development

Important: This development is a small part of the project in order to test the awarded developer. If the developer do a good job and finish in the 3 days, he will awarded to finish the whole project with a budget around $3000. I have a website running on WordPress 5.8.1 (with elementor) and I need few specific features to add in the pages as widgets: 1. Horizontal dynamic slider ($50) As described in the picture [login to view URL], it is a responsive widget (same width as the theme, the project theme will be shared with the developer). By default, there is one button in the widget (like in the mobile illustration with a + icon) to add a child with firstname/gender/birth date in a popup. If gender is male, the default image is a boy otherwise it is a girl image. By clicking on the rounded image in the panel, user can replace the default image by any JPG image (limit 3 Mo). All child panels can be slided horizontally into the widget. An "update" button displays a similar popup to update/delete any child. 2. Checklist feature ($150) A second widget allows to display different categories with image, description, panel color and percent for each category (responsive in 2 columns on desktop and 1 column on mobile). For each category, there are unlimited steps to confirm by the logged user similarly as a checklist feature. In [login to view URL], you can see how the tables must be structured. Only the adminitrator in wordpress backend can add/update or delete categories and steps (you must also add this feature in the backend). By default, the first child is selected (depend on the firstname first letter order) but the user can change of child by clicking on "select child" (a popup allows user to select another child added in the horizontal slider) By clicking on a category panel (image [login to view URL]), user accesses to all steps to confirm of the selected child ([login to view URL]). All the steps are ordered by the field value "nb_days" in the table "steps" in 2 columns on desktop and 1 on mobile. Once the steps is confirmed through the popup, the step becomes grey and falls automatically at the bottom of the list (all the confirmed steps are ordered by the same "nb_days" field). If the field "require_photo" is set "yes", the user must upload a photo to confirm the step. The photo will displayed in the confirmed step panel. If the field "info_description" is not empty, there is a small info clickable icon to show the info description. A confirmed step can be cancelled by clicking the "restore" button and the step comes back to the top of the list with the right color, the right position and the associated photo is deleted (if there is one). The percent in the picture [login to view URL] is percent of steps confirmed by the user for the selected child that has been confirmed depend of the total of the steps from the category. The child list created in the horizontal widget is for one user. Another user can create his own child list.
