Isotope
Isotope is a JavaScript grid layout library used to create filterable and sortable grids with automatic element positioning in the browser. It functions as a layout engine that calculates absolute coordinates for elements to maintain a dense grid regardless of individual item dimensions.
The library features a masonry layout engine that arranges items of varying heights into a compact grid to eliminate vertical gaps. It includes a coordinate-based layout animator for smooth transitions during layout shifts and a CSS selector filtering tool to show or hide elements without reloading the page.
The system also provides a custom element sorter that rearranges items based on data attributes and comparison functions. It manages overall spatial organization through constraint-driven flow calculations and coordinate mapping.
Features
- Masonry Layouts - Provides a masonry layout engine that arranges items of varying heights into a compact grid to eliminate vertical gaps.
- CSS Selector Filtering - Ships a CSS selector filtering tool to instantly show or hide grid elements without reloading the page.
- UI Element Sorting - Provides custom element sorting based on data attributes and comparison functions to rearrange the grid layout.
- Selector-Based Visibility Filtering - Toggles element visibility by matching CSS selectors against a dataset to determine which items remain in view.
- Cascading Grid Libraries - A JavaScript library specifically designed to create filterable and sortable gapless grids.
- Constraint Layout Engines - Calculates element placement based on dynamic container width and specified gutter requirements.
- Spatial State Tracking - Tracks the real-time X and Y coordinates of DOM elements to manage layout state and motion.
- CSS Selector Filters - Provides a mechanism to show or hide grid elements based on CSS selectors and custom criteria.
- Grid Gap Management - Positions items of varying heights into a compact grid to eliminate vertical gaps and maximize screen space.
- Interactive Layout Filtering - Provides an interface where users can instantly hide or show specific items in a layout based on categories.
- Absolute Positioning - Calculates precise X and Y coordinates to eliminate vertical gaps for elements of varying heights.
- Flow Calculations - Determines element placement by calculating available container width against specified gutter and margin requirements.
- Filterable Portfolio Galleries - Organizes visual collections of projects that can be filtered and reorganized instantly to improve browsing.
- Custom Sorting Logic - Provides mechanisms for rearranging grid elements via custom comparison functions applied to data attributes.
- Output Element Sorting - Programmatically organizes grid elements based on specific data attributes without reloading the page.
- Layout Interpolators - Calculates intermediate layout properties between frames to produce fluid visual transitions during layout shifts.
- Spatial Coordinate Maps - Implements an internal map of spatial coordinates to track and update the visual state of grid elements.
- Layout Animation Engines - Automatically calculates and animates visual transitions when grid elements change position or order.
- Coordinate-Based Layout Animators - Smoothly transitions elements between positions using interpolated X and Y coordinates during layout shifts.
- Coordinate Transitions - Creates smooth visual transitions for elements moving from one position to another during layout shifts and filtering.
- Custom Callback Sorters - Orders grid items using user-defined comparison functions and data attributes.
- Table Management - Filtering and sorting for grid layouts.
