An experimental custom element that wraps plain-old HTML (view the source) and decorates function, keyboard handling, accessibility information. It hopes to inform how we approach some kinds of new elements and efforts like OpenUI. It allows for an 'opt-in' UI that is similar to form controls, but by default doesn't provide much. It doesn't hide much from you either - you are in control of your light DOM, use JavaScript and CSS, it's ok. Resize your screen small, it will change the display to something 'accordion-like' - that's not built in, it is 5 lines of js you can add that just set an attributes based on a MediaQueryList. It should respond to DOM updates adding or removing elements too...
Adding a panel dynamically should be possible as normal DOM, it shouldn't lose focus if it is already set.Nutritional Information Lentil Soup Servings Per Recipe: 6 Amount Per Serving Calories: 349 % Daily Value * Total Fat: 10g 15 % Saturated Fat: 1.0g Cholesterol: 0mg 0 % Sodium: 131mg 5 % Potassium: 970mg 27 % Total Carbohydrates: 48.2g 16 % Dietary Fiber: 22.2g 89 % Protein: 18.3g 37 % Sugars: 3g Vitamin A: 4230IU Vitamin C: 13mg Calcium: 98mg Iron: 6mg Thiamin: 0mg Niacin: 6mg Vitamin B6: 1mg Magnesium: 104mg Folate: 334mcg * Percent Daily Values are based on a 2,000 calorie diet.
